Is the rating an indication of how much pressure the springs exert on the valves to keep the valves from floating at high rpms?
If my valve springs are rated for up to .500" lift, can I "get away" with a cam that lifts the valves to .512" and .533" if I keep the rpm below 5000?
I never rev my engine past 5000 rpm anyway.
