Ok getting heads this week or next week, but still unsure of which.

[95blk5.0stang]

Ok I saved up $1600, I want some heads. I want to be really sure that if I'm go to drop my money on some cylinder heads that I'm going to do it right.

My Choice of heads:

1.) AFR 165cc 58's.... I hear they are the best n can use stock components.
2.) Trick Flow wedge....I hear they're second best, but need extra stuff.
3.) Edelbrock Rpm......have money to get LT's n H-pipe
4.) GT40x.... Pretty low on price haven't heard much about.


I want my mustang to sound nasty, I've heard videos of 5.0 with trick flow, but not with afr will my car sound bad ass my mods are.
Now:
Rebuild kit .30 over pistons
Explorer Upper/Lower Intake Manifold
E-303 Cam
BBK CAI
King cobra Clutch kit
Weight Reduction, Back Seat,trunk
Smog pump, A/C deleted
Short throw
Stock shorties,Summit Hpipe, Mac Catback
Cobra R 17x9
Bumped timing.

i have shortys and off road h with the mac catback, and mine sounds pretty good.... i want longtubes and matching h though....

 

[95blk5.0stang]

my stock shorties, with summit h-pipe, with Mac catbacks. Sound good, but I hear LT's sound better and great you 15-20hp increase with shorties are a waste of money.

 

[Hoseitdown]

:dunno: about that, but im gonna try to get a sound clip next week sometime... :dancing6:

 

[94white5.0gt]

i'd go with the afr 165's, that is what i am going with when the time comes. alot of people used the afr 165 heads, and i hear good things from every one of them...

 

[95blk5.0stang]

that what I'm more than like go with is the afr heads, cus you can use them with stock components. I just get hardened pushrods, then get roller rockers later. But my sound clip is on youtube.com under my nice sounding 95 5.0.

Keep in mind the 58cc AFR 165s use stud mount rockers, so your stock ones won't work with them. If you want to keep pedestal mount rockers go with the 60cc heads.

 

[BackinBlack]

AFRs will give you the best power hands down. You have a couple of problems though. One was stated above about the rockers. If you have another $200 or so to blow then go for the stud mount. You'll want them later anyway and stud mount is better. Second the springs that they put on the AFR heads are only good to like 5500 RPM with roller cams and after that they start to float which is very bad. You'll have to upgrade them before you can really use the heads to their full extent.

The other heads are good but not as good. I'm not sure about their spring packages but I do know you can get most of them in either pedistal or stud mount.

What experience do you have with the AFR heads that makes you so sure there the best?
I have run both.
AFR and TFS both make great heads and they will make similar power. Both have ther quirks also, but with your mild cam setup you shouldnt have to worry about the springs they will be fine. If you are planning on reusing your stock rockers you will have to go with the AFR #1472 60cc head. They only carry the 58cc for stud mount rockers. If you plan on getting more radical with your combo you might want to consider the tfs as they have plenty of meet left to port in the future.

 

[BackinBlack]

The reason I say AFR over TFS is because TFS have 2.02 intake valves and and AFR 165s are 1.90. I would rather have the low end torque from the AFRs since it is a street car rather than the top end power.

I would worry about your springs. With the kind of power the heads can produce you will be seeing that 6k redline and AFR says not to use there springs on a roller cam equiped motor that will see over 5500 RPM because the valves will float.

They are both the best heads you can get. It's just a matter of preference.

MM&FF had some great articles a couple of years back where they compared pretty much every brand of head against each other. AFR and Trick Flow were at the top all they way from street heads to race heads.

 

[Stangbangin]

I will say trick flow's leave you alot more room to port later on down the road. If you're gonna run any kind of aggressive cam youneed to upgrade the springs on the afr's because the ones that come won't do.

 

[Urban Legend]

Not sure but does the trick flow bolt right up with the 2.02 valves? I thought I heard that before. Or what about the cnc trick flows?I've got a set of AFR 165 stud mounts sitting in the parts pile I've been waiting to put on.

No matter what, with this stuff your car will always sound like ass. At least that's what I was told... :dunno:

 

[Venom351R]

I have AFR 185's, another thing is AFR's come CNC Ported.

As far as the springs and the valve float w/ an upgraded spring package would the vavles still float at above 5,500 RPMS?

You dont have to worry about any valve float Ed set you up. :thumb:

What about patriot??? They are alot cheaper, and netted some pretty good # in the article they did one them.

yeah now I wont have any issues, I mean before when I had the AFR upgraded spring package and I was winding the thing up to 6,000-6,100 RPMS :hammer:

 

[94Pro-5.0]

i like my trick flows. they have plenty of room to port when i upgrade to a larger cam in the future, plus the springs can handle up to a .550 lift

I have no problems with the stuff Ed set me up with, infact I usually shift around 6200 and have never experienced any valvefloat. I have on occasion brang it up past 6500 with no float either. :thumb:

 

[Venom351R]

If everything goes right and the car is done next week Im going to take a trip to Epping either Friday night or Sat morn providing on the weather. Once I get to the dyno I'll have a better idea of where to shift but I dont think there will be much trouble for this new set up to still be pulling hard in the upper RPM range.
