Dick,
I was able to sneak into your garage and snap a few pics of the Imperial heads right after you pulled them. In this shot you can clearly see the "hot" valves at each end of the head.

On closer inspection it's obvious that one of the valves is pretty badly burned.

Actually, I suspect that Dick's Imperial heads looked an awful lot like the heads I recently pulled off my 66 New Yorker 440. I bought the car this past Spring and it took some head scratching to get it running. It turned out that it had 5 stuck intake valves and 5 bent pushrods. Ouch. Once I remedied that little problem and got it running it sounded pretty darn good but there was obviously still a problem. A very impressive backfire caused the muffler to instantly change shape:

Hmmm, I wonder if there's a bad exhaust valve? With 97k on the clock it seemed prudent to just pull the heads and have them reworked. The machine shop did a hard sell on hardened exhaust seats so I decided to do it (for the first time ever). Installing the seats cost $200. The whole cylinder head rework cost just over a grand, pretty much insuring that I will never break even on this car. I got 8 new exhaust valves, 16 new guide inserts, glass-beading, 3-angle valve job, and surface heads 0.010" I have yet to find the time to put the 440 back together :-(
