I have " for the most part" stopped using head bolts for this reason and have moved most of my motors to head studs.. no broken bolts, a better and more even head torque, less failure or leakage from head gaskets, usally cheeper to get a set from ARP than factory head bolts. If you read the fine print , the factory does not recommend the reuse of head bolts, Very few do.
Just some food for thought.
He is talking about the bolts that hold stuff to the head not the actual head bolts. shawn
