My stock heads are ported, polished and milled with a 3 angle valve job and trick flow springs.
I installed those along with a GT-40P intake and knocked off 7 tenths in the 1/4 and gained a few mph.
I have well over $600.00 in my stock heads but I out run lots of cars with AFR and trickflow heads.
Its worth it if you do it right.
