It's a diesel oil, so it probably exceeds most "car" oil specs. It also has a lot more detergents in it because it's made for diesels.
The reason I put non-roller cam is that oils were reformulated a few years ago, decreasing zinc content (EPA regs). Cam manufacturers started seeing a lot of flat tappet cam failures and blamed it on the reformulated oil. Rotella was not reformulated and still has a lot of zinc. Cam makers reccomend it for flat tappet motors. Your 502 will be fine.
