One of the old myth's on this subject was due to cold air flowing back up the short pipe or headers after shutdown and with the cold air and hot metal causing the valve to wrap .. it is a very old myth.. .
But with much better metal in the Valve these days.. it is unlikely. But I guess it can happen.
