probably bent a valve... Never do that...

I would guess to start with a compression test.. if a valve got bent , chances are it is losing compression. Yes It COULD still start/run fine but power MAY be lost.

Cold seize is more likely, even if it didn't seize all the way, it would have damaged the piston and possibly the cylinder, also resulting in noise and reduced compression. Yes, don't do that...:o
