yes they are hollow stem valves and you can buy just one valve from GM, as far as whats needed to make them useable - i would do both valves in that chamber, you could get away with just lapping them in probably. most likely if i were to keep them and use them id send them out and have them gone through.

what happened is not really clear, car came from another shop running rough after an oil change(was a dry sump LS3 engine) i believe they filled the engine through the valve cover instead of the tank but they swear they didnt. it ran rough and had low compression on that cylinder so i pulled the head and thats what i found. the customer wanted to do heads/cam/intake anyway and decided now was the time to do it.
