cylinder heads ?

[xs man 27]

hey guys i m wondering if anyone can explain to me what cylinder heads they all think work best for 95 gt ? my odemeter reads almost 120 k miles and i m hearding a tapping sound and leaking oil outta of my one tail pipe. was thinkin about the crate motor idea and than i reconsidered with the money you spend i ve been reading a lot of people say to rebuild your current 302 engine and throw some better heads on there . i m confused with the cc of the cylinder heads and what ones i would need. i m looking into the AFR and trick flow heads but besides the two companys i dunno what else i should be looking for ,, i dont wanna do nitrous poss a supercharger in years to come but not right away.. any help you guys can share in on and help me would be great.. any other questions you guys need me to answer will be more than happy to answer... thanks again guys

I have trick flow myself but have never heard anything bad about afr other then price. It would be helpfull if not necessary to know the issues of the motor before its recomended to upgrade the heads or replace the motor though. A tap might be nothing or.....

 

[Musturd]

Oil out the Tail pipes is usually due to wiped out piston rings... The tapping ur hearing could be a sticky or collapsed lifter , or loose rocker

i just wanna replace everything at once if the motor is gonna get re built and apart,, what is the cc in the cylinder head i should be looking into ? any HP gains i should expect with any of the two heads afr or trickflow ? any other parts i m going to have to buy and replace if i get new heads ? currently i have from previous owner 24 lb injectors , crane cam roller rockers and poss an aftermarket cam ( previous owner thought the cam wasnt changed but my mechanic looking at it says it may be an aftermarket we havent took it fully out yet ).. any other info on what i should be looking into when changing out heads and any other parts that should be looked into will be great..

what size cc should i be looking into ?

 

[rz5.0]

Depends on the pistons you are going to run. How high a comp ratio you Want..

 

[xs man 27]

my pistons are stock as of now along with my cylinder heads, however i do have crane cam rocker rollers in and i m pretty sure the previous owner did not install the rocker roller correct and i have valve tapping.. i know the afr vs tf head debate has been discussed over and over.. i m just trying to figure out what cc size would be best to be looking into.. thanks again guys for your help sorry for all my new b questions i do app. the help.. thank you

I think afr is 58 keeps the CR close to stock..

 

[castine917]

Afr 165 come in 58 cc for stud mount and 60 cc for pedestal mount. Stock heads range from 60-64 cc.
with the rest of your budget in consideration, don't buy heads until after your motor is out, diagnosed, and repair costs figured.
You may have already spent your whole budget.

if i went with the trick flow heads what ones would work best ? my car is a street use only no track or racing.. also i currently have crane cam roller rockers the previous owner installed, i dont think they will work w the TF heads so my other question is what else should i look into or need to get when installing new TF heads ? thank you again for your help..

I run the twisted wedge 170's and have had good luck with them as well as with a stage 1 cam by trick flow. I think they are almost as good as afr but can be alot cheaper. I got them on sale from summit shipped new for a grand.

If you get the heads just get pedestal mount and you be able to reuse the rockers..

 

[xs man 27]

im trying to find the mounts your talkin about man, would you be able to help me out and find the ones i would need ? ,, if my roller rockers are not in bad shape i would like to re use if i can and save on buying a new set for the TF heads.. thanks again man

I think tfs stop making pedestal mount.. Afr makes then tho. I.e. could be wrong

 

[ttocs]

didn't think they did them anymore either. You can always sell the ones you have.

 

[xs man 27]

so the trick flow twisted wedge cylinder heads now come with stud mounted roller rocker arms ? in that case what are some good roller rocker arms for the TF heads ? also what other parts will i need for the trick flow heads ? i wasnt planning on changing the roller rocker arms being the ones on there are crane cam ones but like ttcos said i can always put them on CL and if they sell or trade would just be a bonus.. when i do the head swap i would change anything needed or should be changed with a engine with 120 k miles ..
how long does a cylinder head swap job take a car mechanic rough est. about hour wise ?

thanks again guys for your input ,, very helpful and made my decision on the Trick Flow heads now i just need to find what other parts i m gonna need and what cc for the camber would be best.. thanks again

 

[ttocs]

trick flow makes rockers as well. I found some on here I think it was used, SVO brand can't remember what I paid for them.... There are alot of good brands and if you keep your eyes open they are not hard to find used.

 

[xs man 27]

thanks guys for all your input but I made my choice going to go with the afr 165 heads , I have a stock bottom end motor on a 95 gt , can anyone let me know what afr heads I would need ? I also have crane cam roller rockers from my previous build I was thinkin about reusing,, can anyone help me out and let me know if putting used crane cam roller rockers (pedestal mount ) on my new afr heads would be ok n good or if I should buy new roller rockers ? my mechanic ( family member cousin ) whos doing my install said I didn't need new ones and to keep the ones I have. also if I do get new roller rockers would I see any hp gains over the crane cams ? and what brand roller rockers does everyone suggest ? thanks again guys for all your input .. def did as everyone mentioned and buying the afr's, is it all bullcrap about gaining almost 100 hp just from these heads ? cant believe everything your read.... thanks again

I don't think you'll be disappointed with the AFR 165s, if you want to run pedestal rockers make sure you buy the heads that support that. last i checked they made 3 versions of the regular 165 heads, two with stud mount and one with pedestal. the pedestal one should have 60cc combustion chambers which should bump your compression slightly.


If you just have the stock rocker arms it would probably make sense to buy some roller rockers, again just make sure you buy the proper rockers for the heads you're buying.

They are nice heads but don't expect 100hp gain from them.
