Do yourself a favor and pull the cylinder head. A valve that sticks enough to bend a pushrod will do it again unless you do a complete valve job including checking for the proper valve stem clearance in the guides. Go ahead and get a machine shop to fix it right once, instead of fighting with sticky valves repeatedly. You can also get a good idea of the cylinder condition with the head off. Rust pits from a piston sitting in one spot with the valves open on that cylinder are pretty common on engines that are out of use for a long time.
