The only thing that keeps the valves out of the pistons are the springs. The valves can't hit a spark plug, only the piston can. Something came apart inside and smashed the spark plugs. If your valve springs broke or wore out, the valves could hit the piston and then the piston chunks might have been able to hit the spark plugs. To have it happen on one cylinder sure. For it to happen on multiple cylinders....that is just nuts.

If you have a bad brake booster, the last few cylinders run lean and the pistons blow apart.
