Is there a replacement stud that has oversize threads where it screws into the block, but the standard diameter and threads for the exposed portion
Yes there is. It is called a step stud. The end that screws into the block is the next size up and the rest of is made the same diameter and thread as the old stud so you can use the original size nut. If you can't find one any machinist can make you one. BTW Helicoils are OK, We used them in the NAVY, however they are a little hard to use properly and tend to back out easily when you don't want them to. The step stud is, by far, the best solution.
I would chase the threads on the remaining studs and use new hex nuts. Helps to obtain the proper and uniform torque.
