After cleaning up the head bolts and using a die to make sure I didn't miss anything, I ran across two bolts that had faulty threads. One had a flat spot on a small section of a thread, the other had some dings across two threads. I'm a little ticked that they were used in the first place and hope the block threads will be o.k.(I have no clue which hole they came from). After using the die on them they cleaned up o.k., but would it be a good idea to replace them anyway?
