They can be helicoiled, but it's not always permenant. A timesert is however.
a lot of piston chamber pressure and a weaker than usual head plug thread. when you consider how much pressure actually takes place in the chamber, you do have to wonder how any of them stay in...
No updates?

Good work. What sort of cost did you have in the end? Thinking about replacing my leads and plugs.
