You should only need a torque wrench for the first step of head bolt
tightening, to 35 ft/lbs. After that it's a 90 degree turn, wait 10
min, do another 90 degrees. If you attempt to use a torque wrench for
final tightening, you will either break the bolts or leave it too
loose, depending on what you try to use for a torque. These are
stretch bolts, and do NOT have a defined final torque.
Not only that, buy my friend Hans strongly recommends tossing them any
time you take the head off and put brand new ones in. It's fine to
reuse them on the gassers if they aren't stretched too much, but he's
never had a head seal properly for long if you re-use the diesel ones.
Much cheaper than a new head gasket set.
Can't help you on the lifter bore, you might want to take it too a
good head shop and see if they can sleeve it for you.
