No, and I'm sorry I didn't take any pictures as they came off. I can tell you that there wasn't much visible damage - all I noticed was that the 2 cylinders that had shown somewhat low in the compression test also showed that their exhaust valves had been running hotter than the rest of the cylinders. This was indicated by the whiter, bleached out look of the carbon buildup on those two exhaust valves. When I took the two suspect valves out of the heads for a visual inspection, I could see some ridge in the seats of the valves, showing that the valves had sunk into the heads perhaps 0.010" or so, but I did not measure the ridge. There was also some erosion of the seating surfaces - very minor but visible with a strong magnifying glass. This latter defect was what ultimately caused the valves to leak, I'm sure. I decided to replace ALL the valves (this car has almost 130,000 miles on it) and the timing chain and gears, and have the heads updated with hard seats.

Did you happen to get a few shots just as you removed them to show the damage? If so, those would be great to see as well.

Here are a couple of pictures of the heads for my 68 after inserting the hardened valve seats in the exhaust valves. All the valves are new and shiny here, so the seats are a little hard to see, but if you look closely at the exhaust valves (the smaller valves), you'll see a bright ring around them; these are the inserts. I apologize for the black paint - I promise I will paint them the right color before I install them!
