Differences between machine work...Heads

Well, if you've never seen the difference...you really cant tell. And then you're constantly doubting when others tell you different. It's human nature to trust. I would trust both these guys to have fun with and help if my truck was dead on the side of the road. But only one got my work. Only you can tell if you "get what you pay for". My customer with the Indy crate engine is furious right now.
