LS series III OEM bearings... Tri-metal? (Odd wear w/ pics)

Tore down a cheap 5.3 motor tonight. 2 of the mains have copper showing at the upper edges of the cap. Is this normal? I see no abnormal wear anywhere else. Crank looks good. Is this typical of a 100k mileage motor? Anything to worry about? Should I just replace them? What would cause one are to wear like this?

Local had mentioned that some of the tri-metal bearings would wear this way over time (high mileage) and that it was normal. He suggested I just slap it back together and run it.

Suggestions?
