I ended up getting the Time Sert Kit. The M10x1.0 inserts come in depths of 6.2, 8, 9, and 15mm. The 15mm is too long, as the total depth of the CHT hole seems to be between 15mm and 20mm and you're supposed to leave a 6mm allowance beyond the insert. So I ended up going with the 9.0mm insert (which, of course, had to be purchased separately from the inserts that came with the kit).
Anyway, the repair seemed to have worked well. I am now special as I have two CHT's
If anyone needs to borrow this I'll gladly make it available so you don't have to spend $90 for a one-time use. I have one extra 9mm insert but after that you have to spring for the $2.00 and buy your own
