Yet again,my timely search efforts have failed. Does anyone have a good cam install? Ive ordered a set of crower stage 2, the old grind, and they're on there way. Ive got a set of cam gears here too that I'm gonna put on all at the same time. Also I've heard back and forth that you need different springs but then I heard you dont for the old but do for the new. Whats the deal?
