I will probably purchase new studs, but there is a slight looseness in 2 of my studs in the block. I am wondering, if I buy new studs, could I put a little JB weld on the coarse threads and install in the block to strengthen the block threads? I am concerned about stripping the block threads. I did have the same situation when I put the new head on and torqued to 55 pounds. They torqued up OK and did not leak. This time I am wondering if i should try to fix the looseness.
