I agree with everything about wear and heat expansion. The V-Pros are adjusted from the bottom up using a feeler gauge at the valve to loosen or tighten the reduction in valve lift, duration, and velocity vs. from the top down to set a pre-load. So that's the conflict. Adding length if you're setup starts at the top of plunger travel makes sense, but all the published tech info at Rhoads emphasizes the bottom up procedure. Adding length to a rod that's already bottomed out seems counter-intuitive.
