I read through your whole post. Three things stick out to me, both have been mentioned. Posts #43, #45, and #47. Many good ideas from KLXD and Marty.
I would however discount the front crank pulley moving affecting valve timing. You have checked it several times. The mark is on the flywheel. The flywheel would have to move to throw the mark off. Before checking, yes, but after, no.
Leakdown test showed that valves, head gasket, and rings to seal. Good.
So the three things that I question are,
Am I getting an accurate compression reading? They sound consistent, but are they accurate? If after several gauges were tried, measuring protrusion would nag at me, but only after eliminating gauge inaccuracy.
The second, since you had a belt jump, would be the pulley slipping on the injection pump shaft. This would alter the the slot that static times the pump. As I am sure you know, it does not take much movement to drastically alter timing.
Have you ever gotten any smoke out of the exhaust during all this?
The third, oil pressure over pumping lifters.
I feel for you, gotta be frustrating. But from an outside view, that is where I would concentrate my efforts
