You can also try a spark plug tap and use grease on the tap to catch any shavings that the tap removes. Might clean up damaged threads enough to do the job, if you have damaged threads. Vacuum a lot with a probe to catch any small pieces that escape from the grease.
We used some time serts last year on a damaged head with good effect, however, it was in non-through bolt rocker arm holes. I think Ford is using a similar fix on the Triton V8 engines with only four spark plug threads that were produced incorrectly. They are doing it on the car as far as I know and it is working for affected owners.
