Thanks, but I'm going to reuse my lifters. Under 50 passes on them since new. Valve lash didn't change during season no more than + - 0.010"
Also I rolled them on my hand pressing the roller with my thumb and the needle bearings rolled perfectly without any rought spots.
I do check the valve lash after every raceday, one pass or eight passes. Also I keep log if I have to adjust them so I will know if something is going to some direction.
