Need help on some HEADS!

Jaswir · Mar 16, 2009

Going to be doing a head swap on this mustang i just got! These E6 suck bad!

I was goin with some GT40 heads but i was like why not go a lil better!

i saw some Pro Comps

heres the specs!

175 CC intake runners

60 CC combustion chambers

Heads are assembled with new 2.02 Stainless Steel once piece Intake valves

Heads are assembled with new 1.60 Stainless Steel once piece Exhaust valves

All 16 bronze guides

Heads are assembled with .600 valve spirings with hardened valve keepers

Heads are assembled with screw in studs and guide plates

Heads are assembled with new valve seals

Heads are complete and ready to install

I am looking for a Bolt on aluminum head! I will be running a E-cam or trickflow stage 1 cam!

i want to stay under 800 bucks shipped to my door!

Ummm ... what about valve-to-piston clearance? Those '86 motors came with flat-top pistons that (usually) don't have valve reliefs...

I'd say save a little longer and buy something else. You can find used, but perfectly good TFS/AFR heads usually for around $1000, sometimes less. With the 2.02 intake valve, you'll have to open up the valve reliefs on your pistons, which can be done with a die grinder, but would be better to use a piston notching tool, for consistency between pistons. Then, of course there's the fact that they've been out for a while, but are still a relative unknown. Someone on here had them, and IIRC, ditched them after some sort of issues (valvetrain related, I beleive).

Good catch. I didn't even think about it being an 86. You may need to cut reliefs for any head you choose.

see thats what i am worried about... don't know much about heads i have never done a swap...

so only way is take them off and see what would work?

Darkwriter77 · Mar 16, 2009

I've heard it recommended to "clay" the pistons to check for clearance before you go slapping things together. Even stock E7's are a close fit with a stock HO cam and flat-top pistons.

Jaswir · Mar 16, 2009

i would def do the clay trick... just to make sure! i guess i will have to see!

Port a good set of E7's (Thumpers, $600 w cores), and buy an intake, too

strtrcr50 · Mar 16, 2009

TFS heads will give you a fair amount of room with 87-93 pistons. Don't know about 86- though.

Jaswir · Mar 16, 2009

damn this sucks!

KamiKaziDK · Mar 16, 2009

You running a cam with a stock intake?? Putting a cam in is about the last thing I'd do if I were you, you're still speed density I'm assuming? You'll want to get a cam that's friendly to speed density. Might think about just finding some cleaned up gt40s and put 1.7 RRs on them, and then find a good deal on an aluminum intake, would cost you the same as getting just aluminum heads

Jaswir · Mar 18, 2009

i don't want irons... want something a lil better.. i don't care if they dont flow as good as AFR or trickflow...

dont matter anyway gt40 wont bolt up either... no matter what i do i have to notch the pistions

Jaswir · Mar 18, 2009

i was goin to do a intake at the same time
