Two things help in stud removal.  Soak with PB Blaster or Liquid Wrench and
use a stud remover.  I have an old stud remover that I bought at Sears
probably more that 40 years ago when I worked on flat head Fords which had a
habit of breaking studs.  If they don't loosen fairly easily, I would use
heat and more PB Blaster or Liquid Wrench.  Let the liquid work over night.
If you haven't seen a stud remover, they are round, maybe 2 inches in
diameter with a 1/2 inch socket in a cam that tightens around the stud as
you turn the socket.  The remover should be held flat against the block so
that there is no lateral force against the stud that can break them off at
the block.  I got in a hurry replacing the studs in my MG's exhaust manifold
and forgot that and snapped one off in the manifold a few months ago.
Needless to say the neighbors had to shut their windows until I cooled down
a bit.  I wouldn't be surprised if there isn't something better for air
wrenches, but I don't have air.

Good luck,

Dave 72 B

Hi listers,

    On Monday I removed the head and manifolds from my 52TD to send them to
Lawrie Alexander for some of his magic. The head had been on the engine
since I
put it together about eight years/7000 miles ago and I can't recall the last
time (if ever) that I checked the torque of the head nuts.  I was curious to
if any had loosened over time so I began a series of torque wrench tests
starting at 35 ft-lbs and working up in 5 ft-lb increments to see when a nut
might break loose. While testing at 60 ft-lbs I got a shocking surprise as
#4 broke off right at the nut. At that point I dug out my beam wrench and
removed the nuts (most gave way at about 70 ft-lbs).

My concern, and the reason for this posting, is to ask if anyone has any
suggestions for steps that I might take prior to attempting to remove the
from the block.  I'd hate to have one break off at the block level so as to
to be drilled out.  I'll definitely be replacing the studs with new ones, no
question about that.  TIA.
