David, whats the idea here? Are you just trying to free up the engine figuring on it running and not re-building it?
I have had plenty of experience with flatheads and trust me, if they are stuck at all they usually need a rebuild.
The valves may unstick but all the gunk and rust etc in between them and the valveguide can spell disaster. All the valves should be removed and at least cleaned up and lapped back into place.
A broken or bent valve at any rpm can destroy your motor and who knows if any of them are actually bent or broken or cracked until you pull them out.
