Time for some preliminary tests...I warmed up the engine for a half hour (and even tried putting it in gear and low and behold, drive works again!) in preparation for a compression test. I pulled the plugs and the coil wire and propped the throttle wide open.
Here's the results:
Cyl 1: 205 psi
Cyl 2: 205 psi
Cyl 3: 210 psi
Cyl 4: 207 psi
Cyl 5: 205 psi
Cyl 6: 206 psi
Cyl 7: 205 psi
Cyl 8: 207 psi
I guess the rule of thumb is that you want them all within a 10% range of each other. Looks like this is around a 1% range!
And here are the plugs. They appear to be burning nicely for the 443 miles I put on the car in five years. Running on 93 octane plus some 100 low-lead Avgas.
