Success!
I put the plugs back in, new rotor and cap, verified the timing and gave it a shot. It took a bit to get it started. Once it started it was very rough and took some work to keep it going. It struggled for a minute or two, then changed on a dime and smoothed out. It was an instant difference.
Watching the valves, #1 and 4 both released and were working normally (as far as I could see). The car started to idle normally and sounded much better. Still some shaking to the engine but much improved.
Video right after the valves released:
The smoke was something to behold. It completely covered the back half of our property (1 acre) and spread to two of our neighbors. It filled the shop, even with the big bay doors and all the windows open. All mosquitos in a 1000 yard vicinity are dead.
I let it run for about 10 minutes while it got up to temp, then shut it down to heat soak. I rechecked the compression and these are the new numbers:
1 - 150
2 - 155
3 - 148
4 - 149
5 - 152
6 - 143
7 - 139
8 - 0
The valves still aren't closing completely on 8. We don't know what kind of oil the previous guy put in, so we will be draining that this weekend and replacing with Rotella 10W-30. We will also install an oil pressure gauge under the dash.
There is a loud tick, it sounds like it's coming from the front. With a stethoscope it seems to be coming from the intake lifter on #1. It's hard to tell. We may not completely get away from pulling the head if the lifter is bad. But I want to try out new oil and running the engine to see if things settle in and quiet down.
Video of the tick after the engine warmed up:
