i got a built race ported h22 head from my friend, that got it done at skunk2 when they did heads a while back. the was made for turbo.

both int... & ext... valves are rev valves, 1mm bigger, welded chambers, and skunk2 springs & retainers. now im planing to use it for all motor, but i im having thoughts that since the valves are bigger, i cant really use big cams. and that if my pistons are to high it will hit.

anyone got any suggestions?
