Paul -
It should be noted that if you 'over-torque' a sump bolt, you can "pull-up"
the threads in the block. When I first removed the sump on my '67, I ran
my finger along the mating surface. Every hole had a raised lip. After
touching them lightly with a countersink, the surface was smooth and the
sump sealed up pretty well (after I beat the rock dents out of it).
