I burned an exhaust valve once, due to an overpressure situation on a gasser. I drove the car for a few hundred miles and then removed the head. The guide for that valve was completely shot. Several hundred inch/1000 of play. Being blown around due to the imperfect seal (to say the least) apparently put pressure on the stem.
