Re: Over Torqued head bolts =( please help ASAP
You can't thread a 1.25 into a 1 thread. They are course and fine thread and not compatible. You'll have to match the bolt/stud to the thread in the case.
If you have a 1.25 Heli-coil, you'll have to have a 1.25 stud to thread into it.
Apparently the machinist you talked to wasn't too hungry. They charge what they want if they don't need or want the business.
