1275 flywheel- thread fix possible?

Recently, I pulled a 1275/ribcase from a junkyard and found a new, never run clutch set in between. The flywheel had also been refaced. Problem is, the PO had either overtorqued the pressure plate bolts or used the wrong ones because the threads are stripped. Any way I can fix the threads or is it a freshly refaced doorstop?
 
Helicoil, Fidanza aluminum flwheels come from the factory with helicoils in place for the pressure palte bolt holes instead of just threading aluminum, it will work fine.
 
I agree with HeliCoils. Welding may distort or warp the flywheel.

One caveat though. If you are in the habit of using Loctite on clutch fasteners, I would use a very weak (purple) grade (or none at all) once you HeliCoil the flywheel. Loctite has been known to bond so well to HeliCoils that they can back out of the part during future disassembly. I use HeliCoils in aluminum parts at work and I've had to write warnings specifically against Loctite use on those assemblies.
 
I think I'll give it a try. I never use locktite on pressure plate bolts. Never had to.

Thanks guys!
