Anyone local to me capable of correcting errors on a 904 race build

I DID have to heli-coil the starter bolts in my recent CRT built 727. They were stripped out. That was an annoyance I thought I wouldn't have to deal with when having someone build me a transmission - but I didnt bother calling him about it. I'm guessing the young man I saw in his shop didnt bother to check the threaded holes in the cases.
