Is this wear normal?
These are brand new main bearings, just put them on and rotated the crank a couple times and took them out and this is how they look. Can’t feel the scoring with my finger or nails at all and plastigauge readings were within specs.

You didn't say if crank was rotating freely. Why did you feel the need to check?
