I have set what comp cams advice is. Cant remember it.
These RHS have smaller intake cc than my old heads. These RHS heads looks almost too small from pushrod pinch area. They also have 10 times more better looking exhaust ports. and multi angle valvejob that I didnt have in old heads.
Yup, much improved heads and no gains ,again, indicates the bottleneck is elsewhere. Even Comp Cams recommends 3.91-4.10 gears and a 2100-3100 stall for use with that cam.
