Will check the torque in two weeks to ensure I'm still at 65 lbs
(Hi comp head/gasket recommends 65 lbs)

Keith,
Which head and manufacturer is suggesting 65# torque?
From my checking Snyder's website: Their Thomas, 6:1 and 5.5:1 heads all state 55#.
All their gaskets for high compression heads state 55#.
Most of the reading I do of spec's from the manufacturers of both heads and gaskets suggest a torque of 55#. If the head and block are "flat", 55# should do the job.

When I hear/read of 65# being recommended, it is from car owners.
My concern with 65# of torque is that it could pull a stud out of the block if the threads are compromised in the block. There is not much more of a sinking feeling than when the torque wrench keeps moving and the torque reading stays the same or decreases.
Thanks!
