Scott.  Be extremely careful when you oil the cylinder head studs and
screw them into the block that you do not over oil and create a
hydrostatic (or should I say oleostatic ) lock.  It has been known for
people to crack the block with the enormous pressures the simple action
of screwing a stud into cast iron can create.

Incidently, for those who may be contemplating the replacement of the
the spigot bushing in the ends of the  crankshafts of T-Series cars,
hydrostatic pressures does a wonderful job.  Fashion a wooden dowel rod
so that it is a tight press fit inside the bush, fill the cavity with
grease, insert the rod into the orifice and whale it with a bloody big
hammer.  The bush usually blows straight out with a most satisfying
noise.
