Just wondering about this..., say for example when you swap your cam for a wild cam, that can shift most of the power right at the top end of the rev range. Is there any such simalarites with say a stage 3 big valve head? would this shift power in the rev range, or does it simply just make a better breathing engine etc... ?

Thanks.

a good big valve head gives more power all through the rev range but with a little less torque because of the bigger valves
