**Final update**
Two valve seats let go causing the damage.
450 easy hours, motor replaced, no help what so ever from Kioti.....
Thanks for the feedback. I for one appreciate it.
There is near-zero clearance between the tops of the pistons and the valves so if a lose valve seat jammed a valve open that wold certainly ruin the day. Looking at the parts book, I don't see any valve seats so they must be an integral part of the factory head unless the head was repaired previously and new valve seats were pressed in. In any case, this is the only case I can recall where a valve seats came lose.
Good luck.
