I took a trip out to its storage home for a bit. I changed all the plugs, wiring, coil wire and distributor cap. We looked at the ballast, nothing wrong there.

I'll start exploring around the cam, lifters, rods and valves. I think the general consensus out there is there something
Valves sticking? might pull covers and get a remote switch on the relay to study the rocker action. All I got for now, good luck.
Thank you for that, I'm gonna get up with my mechanic friend in the next couple of days and pull the covers off and go exploring. I'll let you know what we found (or didn't find? when we get back.
