Another test along those lines I think might be revealing would be to try and find some lifters with a nice slow bleed rate, then sort through a tray or so of new stock replacement lifters, find the 32 with the highest bleed rate......... then test the slowest bleed rate vs the fastest bleed rate on the cam that ran into stability problems at the lowest rpm...... and the one that revved the highest before getting unhappy.



My head hurts now.

How do the older oem rate? Ive some sets from the 70-s long before they started putting the nice machine marks on them to get the crown.
