Oh yea I just went with zero deck (plus head gasket) which was/is his goal. Forgot to mention that. Before shaving the pistons to set the deck heights even to zero across all of them, I would spend a moment trying to figure out what is causing the difference. Can you think of any other ill effects if the deck was milled at a slight angle? It's late, my head doesn't work right anymore... if it ever does :P
