Almost certainly not. So how about, at least on the shrouded plug, select a much hotter plug and see if it will burn off. From inside that shroud I would seriously doubt it could cause anything like detonation. Would a propane torch be hot enough to burn off the deposits on the ceramic, or would you really need an oxifuel torch?
There HAS to be a way ... Jim S.
I would think the oxifuel would be necessary not so much for the heat, but for the oxygen. You want the excess oxygen to react with the lead/carbor and carry it away.
BTW, if you do attempt this method, make sure you stay upwind. You don't want to be breathing any lead oxides. We have enough half-... on here already.
