Rear Main Seal Install

I am not an engine builder, so I have little experience in this area. How much would be typically machined off the caps prior to a line bore?

Engine is in the car, so I can’t see anything with the cap on.

It depends. But cutting a couple off the cap will move the hole...damn I don’t remember. How far is the seal proud of the cap since you can see it?
