cam selection

That's basically what I meant Terry. No disagreement at all. But someone I never met, handing me a box saying "dont worry, they're all in order", immediately sends up a flag. That's all I meant. The safe bet should the used cam look good is buy new lifters. But now your 1/3 of the way to a better cam (IMO anyway) plus the cost of the used setup. So at what point does one decide to go new? That's an individual's choice.
