On a positive note the intake valve stem is visible and looks like new. I am surprised to find it shiny all the way up to the valve head. Is that normal in a 28 yr old engine?Perhaps the engine was worked on in the past?
If anyone has run into these hard to remove bolts before, let me know how you dealt with it.

The piston has a little carbon on it but not a lot. The exhaust valve looks almost new with EXS 4 or EXH 4 (can't remember exactly) stamped on it. The intake valve has some black gunk on top of it but looks in good shape. I think this engine has been worked on in the recent past and maybe the head gasket wasn't torqued properly or was not retorqued when hot. I'll try to post some pictures soon.
Thanks everyone for all the help! It has been 20yrs or so since I have done this kind of thing.

I need to get a set of bore measuring gauges to find out how far the cylinder is out of round. I will likely end up putting it back together and seeing how it runs. If I can get 50-100hrs out of it that will do until I get a re-power engine or do a total rebuild. I am concerned that the deck of the block might not be smooth enough to make a good seal. How can I clean away the carbon and remove minor imperfections in the seal are?
I am pretty sure the engine has been worked on before. I found a flanged washer in the gunk of the cylinder fins. It looked like it was maybe a valve spring washer or something. Hopefully it isn't missing from the inside. I am afraid to open the valve cover and look.

I keep looking at picture #2 showing the head . Is that a valve relief cut in it ?
Yep, it sure is.
