i have a 94 cobra with gt40 heads on it and some 1.7's. looking at patriot performance aluminum heads but want to know what size i should get. don't want to really cut pistons and don't want to order get and install to find out i have clearence isues. a set of heads are under $1000. i know someone with then and he loves them and is pushing 425 to the wheels of his fox. i need to know 1.90 or if i can do 2.02, chamber sizes, and so on thanks for any help.
Those heads only come with 2.02 intake valves as far as I know. Unless you plan on fly cutting pistons, PTV clearance will be an issue. Spend a lttle more money & get TFS heads, a lotta head for the money & will clear up to .540 lift cam.

The heads you have can make alot of power if you have them worked . I had a set on an explorer short block . Stock GT 40 heads and a B- cam with a trick flow street heat intake and 24# inj. gave me 280 rwhp on the dyno . After I killed a couple of valve springs ..I had the heads gasket matched and had better valve springs and stainless valves installed . I also had the machine shop shave .020" off . Once back on the engine with the same internals ... It made 300 rwhp and picked up 25 ft lbs of torque too . It cost me about 700. bucks . If I had them ported and polished it would have made even more . The cool part is when I opened the hood it just looked like a stock set of heads to the untrained eye . Which is a good advantage in the street racing world . Plus you'll be able to enter the factory stock classes with an advantage . Also the money you save from buying the aluminum heads can buy you a nitrous kit .
Having suggested all this .... if you still have your heart set on the aftermarket heads . Then I would be very interested in your GT40's ... Pm me if you would like to sell . Thanks !
Yeh Andy ive heard alot of mixed reviews about those Patriot heads...if i can recall correctly (in my drunken state of mind) when you were talkin to Ron werent you the one saying you heard bad things too? lol...oh well...good luck with w/e you decide...id say hold out for a few hundred more and get trick flow or AFRs

Those Patriot heads are junk-IMO. Keep your eyes peeled for a set of used Trick Flows. Just my
x2 there some off-shore jap junk..the port sizes vary all over the place..remeber...there so cheap for a reason....get sum used tw heads or edelbrocks or something , ur way better off. kinda hard to believe someone is makig 425rwhp on a 302 without any forced induction an just those heads cam and intake and wat not, id hve to see it to beleive it.
