My point is that it wasn't a chunk.
It was vapor. The combustion gasses turned it into aluminum vapor.

i get aluminum with its lower melting temp. but this was a cast iron head, right? looks like iron to me.

It's a common failure when a head gasket goes on an iron head. Take it to the machine shop and have them weld it with a high nickel rod. They have probably done 100 of them.

I'd say it was making more rpms because it was running leaner than the other engine. Not sure exactly why it was leaning out, but I would look into possible causes.
