Never really got into high RPM HP but from this comment my assumption of valve float is coming into question.
I always had the understanding that valve float was caused by the RPM high that the valves could not close fast enough due to relatively low spring pressure for the RPM. Now it sounds like it is hydraulic lifter pump up that causes the issue at high RPM.
Would someone set me straight. I-I-I'm Sooo Confuuuused!
