If you are using an old shop manual they are probably referring to the old asbestos sandwich type head gaskets. These DID need to be re-torqued at least a few times until they ?bedded in?. If you are using a modern non-re-torque head gasket you should not need to re-torque it. If it?s possible to do I usually re-torque my heads at the 1000 mile mark and then about 15k. OR if the engine has been run hot but not yet blown a gasket. This ONLY holds true for the non-torque to yield type bolts. Most modern engines are now using torque to yield type head bolts. When originally tightened these bolts are put in a state of stretch and should NOT be re-torqued OR reused!! I always back off my bolts about ¼ turn before re tightening them. This releases the ?stiction? of the bolt. Head bolts tend to become stuck in the threads preventing them from being tightened any more if you don?t loosen them first. This is ONLY MY OPINION of what to do. I would ALWAYS call the gasket mfg and get their recommendation since it?s their product. But HEY,,, that?s just ME!
