you could try to do the locking thing with something. If it were me i would use a belt or something of that sort. Theyre are also tools made for that purpose, to hold the cams tightly so they dont move. As far as head studs, Finger tighten them in and then back them off a quarter turn. Use the Oil that comes with the head studs and put a small amount on each bolt. This supposively does something for accurate torque, not sure if it does much though. I havent heard of any secret head gasket tricks so i think you should just install it normally.
