if i may give an opinion.many head gasket failures i've repaired have had a crack in the sealing ring.i'd venture to opine that after the many heatings and coolings the metal in the sealing ring is tempered and can't reliably take even the original torque let alone an increase without cracking.

I'm told that it is iffy, but if it is reused to torque it down several more ft.pds. Sure, there's some crush, especially the metal rings around the cylinders but it's going right back on (obviously) in the exact same position. In this case it is for a 750 block and I'd really rather not torque it any more than necessary.
