I just wanted to highlight that Lews ported stage v’s are a huge step up from a set of untouched 452’s...... so it’s expected that there would be very little difference in power between them and a set of RPM’s.


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 muchbeing they ARE a big step up from 452's? Just asking to learn..
the rpm's will help your performance. just use the 84cc head. my guess would be in the 40hp range increase, BUT pay careful attention to rocker and push rod geometry with the rpms.
