  I disagree.....with several points you made.
  In my opinion, putting a few more ft/lbs on each bolt will not hurt =
anything.

    DONT do that. when installing, you tighten them to a specific =
torque, then exactly 1/2 turn more. that last 1/2 turn is what =
compresses the head gasket, and can require torque easily exceeding 100 =
ft-lbs. the trick is that some bolts may require less torque to go their =
1/2 turn, so its actually normal to have slightly varying torques on =
your head bolts. the ultimate goal isnt to reach a specific torque, its =
to evenly compress the head gasket. messing with the bolts _at all_ =
after that point will risk breaking the gasket seal.

      I was just looking at my 9a sitting in my garage and it got pretty =
cruddy over 1.5 years it was in my car. I have a sneaking suspicion part =
of that crud came from the head gasket area. I used the ABA gasket and =
it ran great when I took it out so I don't think I blew anything, but I =
was wondering if there was any way I could "adjust" the headbolts to =
make sure. Maybe just to make sure they're on torque or even maybe give =
'em a hair tighter??  Any thoughts?

      TIA, JT
