And that’s why I don’t mix studs and bolts. The stud needs more torque to get the same stretch so you have two different torque values on the same cap.
You change the torque valve and you can bet you will change the size/shape of the bore.
Chrysler used bolts because they are cheaper, not better.
You are in New Jersey. I find it hard to believe you can’t swing a dead cat and find someone with a mill to machine the cap down.
