I'm thinking that diagnosis is important. How do I know the leak isn't stemming from the block? The head really did look ok. Perhaps I take the head off and ask machine shop to check. That way I can know for sure head is at fault. If that's confirmed then I can have them prepare the other head I got at ChowdahQ.
