I'd say if it passes any one of those tests, it's still in good shape. The "45 degree angle test" was shown to me by an engine builder / modifer whom I have a lot of respect for. If any of the above methods is the "right way", I would put my money on that one.

It sounds like I made out good on the engine. I hate buying stuff on ebay only to find out that I've bought a boat load of crap. I'm strickly a NIB kind of guy these days.
