Jim's got it right, but torque the water, intake and exhaust manifolds to the heads BEFORE starting to do the head studs. Also if yours has been apart and back together again more than once pay attention while you're torquing the studs and watch for bolt stretch. If you get one that takes wa-a-a-y more rotation than the rest once you get close to 100 ft-lbs, it's stretching and the only fix is a new stud. Had a couple on mine do that, FWIW. Good luck with it!

Torque to --100 ft-lbs: Get it hot and re-torque (you will need an offset endwrench to socket adapted to perform the re-torque)
