Correct and upgraded Screaming Eagle oil pump

I wouldn’t trust the S&S cam plate if not using a straighten and welded flywheel, cuz if it develops a runout higher than 5 thousands, the brass bushings cold twist causing the oil feed holes of the bushing to misalign with oil hole from the plate starving a lot of engine components of oil. The brass bushings from the S&S cam plate has no splines to prevent twisting the S/E cam plate does and won’t twist, and are designed to handle up to 12 thousands of runout.

Don't get me wrong, if this is in fact the case, it might help me make my decision
I am now torn...

I think one of the advantages of the SE one is that the brash bushing is key'd in so it cant rotate like the SnS one can.
I doubt this has much to do with run out tolerance but I wonder if it helps.
When I pulled my SE plate out and looked at it I couldnt see any witness marks or anything that would make me curious or worried about run out, and I never measured the run out of my crank.
But I also installed it with faaaar more focus on trying to ensure it was centered.
I described the method I used to Master Tech Miller a while ago and he said I've got nothing to worry about.
I am curious how they managed to allow out to 12000 though.
