This might be the appropriate time to review the steps for re-torqueing head bolts. I know if you just throw a torque wrench on them set for the max head bolt torque it's going to just "click" which may not actually be representative of the actual bolt tension because of the additional effort needed to break them loose from their static state.

If I remember correctly you need to actually loosen the bolts first and then bring them back to the specified torque - correct. Back them off 1/2 turn in reverse order of the pattern for torqueing them?? Does it matter how far back you go?
