I just bought a beautiful mess... care to express an opinion?

Spring is broke and appears to be keeping the valve from closing. I'm not saying the valve is not bent, but I don't see how it could happen. I'm going to replace the spring - because I'm this far into it and it seems silly to not try. I'll then do another leak down test before I put it all back together. If it fails that test then the head comes off. Is that a fair line of thinking?

If the valve is good you can do a leak down now with the cams out and the spring off of the valve. if it does not seal valve is bent.

Pull the valve back while pressurizing (be the spring). If the valve does not seal under pressure it's very likely damaged. If you put the motor back together and run it you stand a good chance of dropping the valve. As you have a very understanding customer, that may be an ok gamble for you, because there is a chance it could be fine. It really depends on your level of risk acceptance. Me? If the valve did not seal perfectly I'd drop the head. listening to the motor crump after all that work would be just too painful. Keep us posted
