With graphite head gaskets you pretty much have to retorque. A Supra 7mgte, mine for instance. I did a retorque after five or so heat cycles and all the nuts (head studs) were loose..as in not at the 80 ft/lbs I originally torqued them to..

This probably isnt as important with a Honda motor as the block and head are both aluminum but 7m's use a iron block and aluminum head and they are known for their blown head gaskets. And it really isn't as important with a MLS head gasket on most motors...But on a 7m it still is.
