I have always loosened and re-torqued head bolts, in the correct pattern, after an engine with a new head gasket has been run a couple of times. It only takes a few minutes, even on a V8. Cheap insurance. I've never had a blown head gasket. When I ask, friends with blown head gaskets usually say they followed the instructions that head gaskets don't need to be re-torqued.
