In theory they would work, but they often have the fire ring land on the edge, or just off the edge of the bore chamfer.
If they are like that, the wire gets pushed down into the bore, the combustion gasses get behind the fire ring and torch the gasket..... And then usually the head and block.

I have repaired several motors where this happened with 1009's.
