Head Decisions for 2v

[KillNThrill24]

I'm tired of my dog ass slow turd 2v so this winter I'm trying to decide if I should do a new shortblock, turbo, or heads. I have a bad feeling if I do turbo I'm gonna blow out my bottom end being 144k old. So my guess would be the heads would be a MUCH safer route. So I'm trying to figure out what would be a good head to go with? And maybe a good cam too. I'm caught up in between MMR stage 3 heads and TFS heads. MMR sells ported TFS but the stage 3's are $3k alone so I'm NOT trying to go that far in debt lol

Here's a link to MMR's 2v parts scroll down and tell me what you guys think. Maybe duff daddy can give me some good insight since he's a 2v pro

I see the link you have to click on products go to sohc parts THEN scroll down lol

Vortech it and be done.

TFS heads cant be ported, A very good friend, and one who is highly respected in the modular cylinder head community has seen time and time again how thin the water jackets are on the TFS heads and that becomes an issue with porting. So if you go tfs, great just DO NOT port.

Personally With your car fun being 300+ hp and a mid 12 second car would be ported pi or stock TFS heads, a decent set of cams (if stock heads, then id go with a 270/278 from comp, some springs and get the cams degreed) if its the TFS go with one of their grinds. The top end kit from Trickflow can make great power but I hate that manifold, Its too big, too heavy and holds a shit load of heat, and personally I have yet to see a manifold make better power, hold less heat and be cheaper then a stock PI YET.

I am personally not a big fan of MMR stuff. If i wanted my heads ported and Nick didnt do them, they would go to fox lake. /thread.


I think that touched everything pretty easily. If you can make 300 and can drive you can have a mid 12 sec car easy.

Not feeling centri's man.. Really not. No offense to everyone who runs them but they just aren't my thing

Good to know about the TFS heads I hadn't don't too much digging on the matter yet to be honest. I'm running a Bullitt manifold on my car already, so I have the big heavy, heat attracting bastard already lol, but I have to give my honest opinion man. My top end has DEFINITELY gotten stronger and I've proven that on the track and the street. It does me better on the track tho. Buddy of mine who runs a stock PI manifold and has a few more ponies (literally about 6), I was catching like a speeding bullet coming down the track. Literally our MPH differences were quite drastic considering how close our cars are in power and everything else. On the street same thing. Tho he beats me every time. The low end is probably less than stock I'll give it that but high end is worth it.

So in your building experiences.. Would you recommend ported PI or stock TFS? Now that you've helped me narrow it down a little lol. Thanks Duffy

Honestly if you are only looking for 300rwhp n/a you dont even have to mess with TF heads. You can run MMR stage 2 heads and any set of custom grind or comp/bullet/cms/etc cams and get you there not a problem. It really depends on what your goals are and what route you want to go and how much $ you want to spend. It doesnt seem like you are too set on having an ET record setting car or a dyno queen so I would just get your 2v's ported/polished and some aftermarket cams and call it a day. Just my .02

 

[KillNThrill24]

Good points man sorry I never specified the power goals I'm looking for. Truth is, I'm going for as much as possible man. Aftermarket heads, forged lower end, boost... I want to do as much as I can man

Got ya. Than if thats what you are going for I would definitely look into TF heads. I agree with Duffy too about any sort of port work on them, I would just stick with out of the box heads. One other positive is with offset retainers you can run any size blower cam and not have to worry about ptv contact or notching pistons. TF heads, custom grind blower cams, and high boost has the potential for some scary high numbers. What power adder and manifold?

 

[Caboose302]

I can vouch for Fox Lake. I have the Stage 2 porting and my car (when the engine was newly assembled) laid down 299rwhp and 338rwtq in spite of the teeny tiny cams it had. They weren't much better than stock. On nitrous (with a drag setup)it ran 12.37. Off the bottle ran 12.79 IIRC...

im looking to do about the same as you with my Bullitt. So far im thinking a forged 5.0 stroker kit with dish pistons, the TFS heads, some long tubes, o/r x pipe and magnaflow catback, and a Kenne Bell to top it off. Only thing I haven't really decided on is what the cam specs will be. Id like to get to most streetable power with out it becoming a track only car and can still handle daily driver duty.

Right on man then ported TFS are OUT. I'll start saving up as soon as possible. And the ability to run any size blower cam is tits IMO. Because lord knows most of us can't afford to do heads and a lower end all in one go around. I'll be staying N/A for awhile if I like the power the heads and lower end add.. The plans are *at the moment* are TF heads, boss 302 shortblock bored to 5.3 and fully forged, and turbo. I would really like to retain the Bullitt manifold as I really have grown attached to it. The high end I get from it is pretty freakin awesome and is definitely noticeable and changed my exhaust tone, making it louder. Unsure on the turbo as of yet. If I follow through with the current build I don't think I'm going to get the On3 which is what I was initially going with.. But we'll cross that road when it get's there.

Those are some impressive numbers man! I might have to do some digging on them, but from what I've heard they are hard to get your hands on now and are kind of pricey too? I'd be totally cool with a 12.79 at this point in the game

I hear you on the streetable part man. I'm running mine as summer daily myself. KB was going to be the first runaround with mine but after many many many changes in plans I think I've FINALLY landed on my full build. Yours sounds like it will put down some crazy power. And since you have a buillitt either hold onto that manifold for another build or be dead sure you won't want it again before you sell it. They aren't easy to get your hands on. I definitely love mine

 

[JerZeyStangz]

No prisoners, I am going TFS 44cc with there run of the mill cams and try to find that ultra rare P51 manifold. I know I am going to be shelling out serious coin but hey its a good foundation to have so when I forge the engine I dont have to buy anything except internals. I dont like the TFS manifold from what I've seen and heard. I really like P51 from fox lake because there is virtually no power sacrifice in the low to high end.

I doubt ill be building anything that ill need the Bullitt manifold for so it will more than likely be sold to help fund the build. Plus it helps that I sorta own two Bullitts, technically one is mine and the other is dad's but ill end up with it one day. Mine is bone stock right now and dad's the only thing that we can see done to it is an o/r x pipe but it has to have something else done the way his pulls compared to mine. So far ive got a rough estimate of 10K in the build so its not gonna happen any time real soon. I hope to be able to go ahead and get the KB soon as I get my Christmas bonus this year and run it at a low boost on the stock motor while I build my funds back up for the rest of the build. And to put another damper on my funds im really wanting to sell my truck and get a Lightning also.

I'm considering saving and shelling out for it myself. I think the ability to buy it all as a top end kit is freakin sweet! I'll price it all out individually but something tells me this is a good deal. Sounds like your build is gonna make for one badass car man. I like your style of thinking

I'm hoping we get bonus's this year haha. But that's sweet as hell man. Sounds like you've got your build all laid out for you, now just hold to it! That manifold should get you closer to a grand depending on what your selling with it. Which will help a LOT to fund your build. I'm thinking of going through all my inventory and cleaning out a bit. I have sooo much shit lol

What is all this nonsense about *not* being able to port TFS heads..... then praising Fox Lake? HELLO........? Fox Lake ports TFS 2v heads! And they get a extra 30 cfm on the intake side!

I would go with ported pi, just because of the availability of them, if something happens you can always get another cylinder head or a pair of heads on the skinny. Hell I know of a set right now ported, and havnt been on a car for 1500 and its a steal for the work that was put in to them.

The bullitt manifold is good, it flows better then pi in certain ranges, and has some good qualities, however the price, the things you have to change and the number of them out there is what turns me off. If i was going to be building a Factory stock motor, then by all means I would have one. Im not and I can do what I want, so Eddy it is for me...

[MENTION=13900]metalman302[/MENTION] its not saying that people wont do it, or dont sell it. Its that if im buying a tfs head, its not going to be ported by anyone. Fox lake does good work, they have been in the game a long time. However, the fact is the water jackets on the cylinder heads are close to runner ports and it doesnt leave much material there. I have seen more then a few have issues with leaks or seeping. I dont want that on my ass, and if your that concerned with the extra cfm, why not just buy the race heads?

I'll have too keep that in mind. The TFS heads aren't exactly cheap.. But I'll do some flow chart comparison's to see the differences. But that whole ability to run big cams without notch pistons thing is pretty awesome IMO, as is the better spark plug threads... Been there done that. Had to change the head out from that lovely spark plug issue.

And yes I totally agree the amount of things you need to do to swap the Bullitt manifold is quite excessive, but IMO, it was totally worth it. I got my manifold/tb/cable/tps and other accessories for a good price, so I went with it. The Alternator was the one thing that killed me. $200 for a Bullitt alternator then had to order a special adapter pigtail to adapt from the old alternator to the new one, modify the valley coolant line..... But I don't regret it one bit

Thanks for the info Duffy I'll keep looking around see if I can snag up some TFS for a good price by Christmas time

 

[chris91]

You can run bigger cams with most of the ported heads as they are running slimmer valves too. Another vote for Fox Lake here.

 

[KillNThrill24]

What kind of prices are we looking at for Fox Lake?
