Ok, so if the stave V's are a big step up from untouched 452's AND the stage V's are similar in power to the RPM's, then why wouldn't those RPM's help me much being they ARE a big step up from 452's? Just asking to learn..


As I said already....... a 40-50hp gain.
That’s about a 13% increase in output by simply installing a street replacement style head.

That is a big step up on that type of build.
