Certainly getting way out of my realm of limited knowledge. Even if they're trying to sell you something, I'm sure they know FAR more about it than I do.

I do have a set of higher ratio roller rockers on my pushrod motor - which result sin a bit more lift, whatever cam your using. And it's pretty easy to swap back and forth with stock rockers - like 15 minutes or so. I haven't done that in a lonog while, but I recall it being a nice sprinkling more more power noticeable over most of the RPM, range, but jsut barely so down low, much more noticeable up high (6000+ rpm). The PV's motor is made to rev, of course. Most of the parts on it are all geared toward making power at high RPM's. Carbs/head/cam/exhaust.
