So the chain of events looks like broken valve spring, dropped a valve, piston hits valve, bends pushrod. Did you pull the head? If the piston is fine, I’d replace the valve, seal, spring, and push rod and ride on.

Heard a bang after a random no start so I towed it home, spark plug 8 tab was touching the electrode lol.. Cylinder looked empty and no marks on the top so I was hoping not to pull the head and just replace and go if possible, which sounds like is gonna be ok? I'm selling it when it's done anyway
