Like I said it is just a buy time method. I wouldn't replace a head gasket to do this. But if the truck is together currently and your wanting to go more then go for it. I have done it personally with no issues. Have actually talked to a few guys that were doing this before head studs were even available. Head studs are a better route. Is your torque wrench correct?? Just curious you don't hear of too many stud failures. Trying to look at all options. As far as the head studs not designed for a retorque. They can be retorqued there is a length spec for the stud. If it is longer than that spec it has stretched. Also these engines weren't designed to run 600HP either. LOL
Studs are a better option no questions about it. Retorqueing the head is an option though. Call Haisleys and talk to them about it. Last year Terry Coppess was still running the stock head bolts and he as pushing 60PSI thru his motor. Patty told me he checks his head bolts religiously and if one feels soft he just replaces it.
