Welcome here! :D

Sounds not good. So you need a complete 81 or 82 head with the cover and almost everything inside. I think it makes sense to look and ask for that instead of collecting the single parts. This also may save reaming valve stems and maybe even lapping the valves.

And you need an oil pump, so I am curiuos what happened there. Did you already check the oil sucktion funnel at the oil pan? The metal filter screen should be clean and moreover there should be two intact O-rings at the funnel stem where it is plugged into the engine.

I would like to buy your old parts for repair. If you have not found the parts yet I have two complete sets. one newly rebuilt and the other in good condition.

Do either of you still need engine parts?
