That's right. The engine was overhauled about 3 years before it was parked in the mid 70s.
Ya it is black beauty sand. Do you think that might work? If not what do you think will? I'd rather avoid using a tumbler to avoid chipping the valves.

That's something I never thought of. That might work.
Keep thinking. Maybe a piece of denim might work on the easier stuff.
