Cylinder Heads 101

Scarecrow,
We use to do the same things that your talking about, but when we found this other info that worked better then we used it. The heads showed a 20-40 hp gain depending on the cam and compression used. We went from running low 12s with the 360 heads to running in the upper 11s with the 318 heads, then we ported the heads and changed the piston to what the forum has and the car ran in the low to mid 11s.
