thanks Ross, that helps me a lot to visualize where the noise could be from. I know the valves weren't stuck before I ran it, as I had the covers off and looked them all over as I turned the engine with a socket slowly - everything was moving freely. That doesn't mean they weren't stuck at some point in the distant past, though. Who knows what it went through before it got parked for good.

The noise doesn't change as the engine is accelerated, and the oil pressure has been determined to be solid.

If some of the lifters are blown like this, can I run it awhile without cracking something? Sounds like another winter project is added to the list.

I'll assume the tappet bodies are mushroom heads, or can they be removed from above (barrel)?
