It took me a couple of days, but the head is now off my '73 Imperial. (Note to the wise: drain the radiator AND THE BLOCK before removing the exhaust manifold and head. I got a wet surprise -- twice.) The combustion chambers seem to have more than their share of carbon. I can't tell if the valves are recessed or not, and would appreciate it if the experienced mechanics among us would examine the photographs I took of the top end.

There seems to be a partial blockage in the oil passage to the forward rocker shaft oiler. The tip of the stem of the exhaust valve on cylinder three is gouged. >From what I can see by peeking through the intake and exhaust passages, all of the valves have a fair coating of carbon, and the stems seems to have a sticky amount of varnish. I guess that the next thing to do is to either rebuild the head myself or take it to a shop. Right now, though, I need a rest!
