Those are pretty crazy all over the place compression readings.

I hate ever pulling a head, but it WOULD give you eyes directly on the situation. I'd lean away from timing being off a notch or two, engine should run the same all the time...pretty terrible.

The miss in the no 1 cylinder is a new symptom to us here, i was under the impression that it ran great all cylinders once warmed up. If there really is no compression there, that's a horse of a different color.

Are there different length Packard valves? I'm not well versed in the subject. Maybe someone installed a valve that physically fit during the rebuild but isn't the correct length and so it's not opening the intake or leaving the exhaust open?

You could also take the valve covers off and check to see that all of them are moving.
