I know the valves can't hit a plug, but if the heads use replaceable valve seats and a seat came loose, banged around head area as the valve cycled and fuel air charge is pumped thru the cylinder, the question is; could a loose valve seat reach the plug to inflict the damage as seen on #5 and #6? Kind of like the valve seat doing the hula hoop around the valve stem as the valve cycles.

It's all probably interesting discussion until the head comes off.......
