heads


do you think the trick flow tw heads would be better than my stock heads on my 90 gt.. ive already got the tf upper and lower intake, 70mm accufab tb and egr spacer and a 76mm straight shot mac performance intake.. im also about to up the fi to 24lbs and get a fuel pressure reg and i havent made up my mind on the pump yet(190 or 255).. what do yall think?

I run the trick flow heads with trick flow intakes and cam and love it. I run 30lb injectors and i would have to say go with the 24lb'ers. I also have the 255 and would go bigger and if I were you go better and have room to grow instead of having to buy another pump or injectors if you keep doing mods.

Yea much better. The stock e7 heads are the downfall of these motors. I wouldn't upgrade to the 24# injectors until you change the heads.

The 24's are perfect for the TW's, just don't install them when you still have the stock heads, it wont do you any good. Put them in at the same time you put the TW's in.

I couldn't tell you for sure there. You might be hurting yourself with that intake and stock heads, you might not. The difference will be minimal at best anyway. If Tmoss drops by he could answer that better than most.

Depends on which trickflow intake you have now. Is it a track heat or street heat??

You dont need damn high ports for a mild 302 they require special headers and the valve cover rail is raised.

stick with the standard tw head

The heads will work fine with the stock pistons, i would probably call a cam grinder for a custom grind or go with the trick flow stage 1 cam.

The very first one I know it is not a custom grind but is better than the abc cams.
