Torque Spec Question. 120-130

Finally a question that has nothing to do with fuel...

My B18 had an original AC. The AC unit was long removed, but the original owner left the pulley and bracket bolted to the head. JoeJump needs a pulley setup for his PV's AC, so as part of a trade, I decided to remove mine - after all, my cheapo FPR has been banging into it for over a year now.

Wait... this does have something to do with fuel... kinda...

So... I removed the two headbolts, but first I use my torque wrench to check the present headbolt torque. Both came in at 110-120 lbs-ft. So, after I removed the bracket and replaced the bolts (with appropriately shorter ones), I torqued them back to 110-120 lb-ft.

I grabbed my haynes manual later in the evening and check the spec. According to Haynes, the head should be torqued to 61-69 lb-ft. Is that correct?!??! That's way below where they started. Am I at any particular risk with the torque so high? I dont; want to loosen them for fear of blowing my head gasket. I'm already a bit concerned about that, but this engine will soon come out...

Incidently, here's a pic of the bracket for those of you who have been wondering...
