Lol!!! Yeah those guys worship the GT-40 head God! Everyday there's a new thread, "Just another 300rwhp GT-40 head setup." They also love the bumped compression of the GT-40"P" head. I love reading when people ask what the heads have done to them. Usually it's stock with mild port work.....okay.....! There's also a guy who swears by the B cam and GT-40 set-up.

 

Ive been hearing the AFR's arent as good as they seem. I know some guys making good power with AFR,but from what I have read Trickflow is the way to go. But its your money,spend how you want.

 

I hear yates are good too
