212- If she was running great, seems like the thing to do, if you want to pull the head for safety, would be to inspect all the spark plug threads closely and see if all should be replaced, or just the one. Plus check the valves, guides, pistons, etc. If problems there, a general rebuild would be in order. Does not sound like you need a total rebuild now unless you find something else. Whatever aluminum bits from the threads went down there are likely long gone by now, possibly even blown past the spark plug on compression.
The alternative to Helicoil is Time-Sert, but we would need our pros' opinions on which is better for this application.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
