Instead of going camping this weekend, I decided to work on one my vans with a stuck engine (silly me).

Pulled engine, noticed two AMC heads installed by a previous owner.

Pulled #1,2 head, noticed this fun stuff inside; #2 exhaust valve was broken off and banging around inside the cylinder.  I guess that is why the engine would not turn :)

Perhaps this is why everyone says when you use AMC heads -- you should install better exhaust valves than the ones that come from AMC?
