Here's a post on Speed Talk about using abrasives to help seat rings, during a build, as well as after an unsuccessful breakin:

A I did SBC 400, with chrome rings, rings didn’t seat very well, can’t remember what abrasive I used, didn’t work out very well I can tell you that. Had to do whole thing over and got rid of the chrome rings, which I’ll never use again. It was a mild build, he did end up running 11.60’s happer then a pig in chit.
