I just may do that. That's 23 of them to do. I had the machine shop do one when they did the valve job. The threads came out with one of the bolts when I disassembled it.
When I took the "topic of our discussion" bolt out an hour ago, the threads came out with it also. At $17 a piece, (what the shop charged) I'll save a bit doing it myself.
