Good point - I'll have to inspect up in the valve guides. Nothing obvious on the valve stems, though.
And, since I'm not convinced I've really got a smoking gun even yet, I'll go ahead and pull the cylinder off and inspect the piston / rings. Cylinder walls look good as far as I can see, but I could have a stuck ring(s).
Meanwhile, my new head gasket shipped and says it should be here by Tuesday. So, hopefully by mid-next week, I'll have it back together and see if I have compression.
