Sounds more like it will turn 340 degrees but not the last 20. The fact that it was 'stuck' until a bit of pressure was applied in the 'correct' direction indicates something has dropped into the combustion chamber. You're looking at a rebuild of at least the top end. Whatever is stuck in there has already scored the cylinder enough to have been wedged between the piston and cylinder OR it had the piston hammered down on it hard enough to lightly weld itself to the piston and cylinder locking them together until you broke it free.
It could just be a ring that self destructed and wedged itself in there. Part of it causing the piston to 'stick' and another piece wedging a valve open at the seat. Whatever is in there now was also in there when the motor was at operating speed. No way you're getting out of that rebuild.
