Just an update for anyone interested.
I was able to cut the aluminum head (of the spare machine) away from the valve guide and get it out W/O incident.
It was tapped back into the good machine with RED LOCTITE and a bushing (as not to damage it.)
Turns out, the original exhaust valve WAS slightly bent on the upper end of the stem (un-usable). Steel cam gear (shown) also had some damage as did the cam itself (some sort of mechanism behind it,???)
After a complete tear down of both engines, removal of the good valve and then waiting on new roller crank bearings and new lower seals, it was assembled.
Swapped some other parts but that's the basic's
Crank, rod & piston with new crank bearings and cam gear installed:
Long block assembled with Yamabond:
