Lifter plunger in the 59 deg toilet

You had a .070 preload?
Can you take apart another known good lifter for a side by side comparison?

The 59* angle isn’t a very good one. The race block corrected that with a 48* angle as you know. It may be time to switch. I’m unaware of your build particulars. 7500 is a lot of rpm. Never mind your occasional plus.

I was setting preload to .045" . The marks on lifter were about .070". I'll take apart another pair of good lifters once i get my new set.
Just wondering if the push rod plunger rotates?
