valve stem seal nightmare

When you tried turning the engine with the valve resting inside, you might have hit the top of the head with that valve. It was probably resting on top of the piston on side, and it was pressing the piston down on that side. the piston isn't true anymore - it probably seats cockeyed in the bore and is wedged with that valve. I can be wrong, but this is what I think happened. Try to find someone that has a snake cam and slide it inside the cylinder to have a visual how things actually are. It might not be that bad. Once you know 100% why the engine is not turning/how the valve is caught, you might listen to the AGA guys and go from underneath without pulling the head. You have to know which way to rotate the engine, if you can remember 100% which was the rotation sense (clockwise or counterclockwise) when the engine seized, so you can try to go the opposite way. You might need a helper and build a small hook out of sturdy wire to pull on the valve to dislodge it. The snake cam and the hook should be able to fit through the hole. the sturdy wire might need a small bend before the hook.
