it blew the plug out of the head?

It's not entirely uncommon, luckily helicoil kits hold up fairly well, most people simply replace the head but that takes time and a good deal of $$

Well the old plug screwed back in, I dunno maybe it was just too loose in there. Anyways I'm going to see how it holds up now before i rethread it.
