I've finally got to the main bearing install on my rebuild of the '56 230ci motor. The machine shop didn't need to do anything to the main journals or con rod journals except polish them. They were ground .020 on the previous rebuild and my Bernbaum bearing set was also 0.20 over. I followed @keithb7's video and plastigaged the mains and they all came out .002 clearance. Spec is .0005-.0015.
Should I worry?
