After building many engines over the years one thing I have notice about bearing shells. If you look at the backside of the shell, some shells are laser etched with name size ect. others are stamped. If the stamping process gets carried away (stamped too hard) material raises up causing a tight spot. Removing the raised material around the letters/numbers with a file fixes the problem. Remove only the raised material being careful not to file away any of the surrounding shell.
