Ever gotten money back from a machine shop?

I know everyone can make mistakes or be forgetful. I have. I would of talked to him first as it could be his flunkie that assembled it. Their isn't a lot of ppl that know mopars especially when the work on everything else out there. In this case I would be wondering if there would be any problems with the rotating assembly or valve train issues. R the cam bearings installed properly. As is this engine grenades we all know u own it. Kim
