Magnum Cam Bearing Bores Scored

The only time I've seen cam bearings like that was in my 392 International. They looked just like that and had lost enough babbit that the cam gear to crank gear centerline dimension decreased to the point it took teeth off the cam gear. Replaced them and all was good. One of my buds thought the failure was due to fatigue, I have no clue. Bottom line, I'd still just replace them and not worry.
