I'm replacing the cam bearing on my 4.8 and so far have ordered two sets of dura-bonds. First were the CHP high performance and then the standard CH set.

I bought them from different seller on eBay and both of them arrived with really poor machining on the edge of the bearings and small nicks leading into the bearing surface.

These were sold new and from top seller so I'm surprised this happened twice. Can someone share there experience buying new cam bearings? Am I getting unlucky here or should I expect the bearing to have rough edges and imperfections in bearing surface?

Pictures would help.

The far edges aren't important, they will get nicked just from install. The chamfer leading to the actual bearing ID should be deburred anyways so that the cam won't get hung up on the sharp edge. I use a little debur knife with a radius edge.

The main thing is that there aren't any issues with the bearing ID and that the oil holes are not blocked.
