You probably haven't done much to the bolts it you're talking about 1/4 to 1/2 of a turn or so for each bolt. Maybe even squeezed the head down just enough to keep that trickle of oil from getting past the water jacket.

If you ever decide to LOOSEN them for whatever reason, and then re-torque, you are going to be in for a blown head gasket for certain.

Had a Chrysler Conquest with the same type of head bolts. Did some head work, and replaced the head bolts with new APM head bolts, designed for the one-torque applications only. Other owners of similar models continued to have recurring head gasket failures because their mechanics would reuse the head bolts.

Lesson learned.
