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!

Bratton's, head gasket #8090, instructions in the package states 65 lbs.
Also installed new head studs and the 6 to 1 hi comp head #8010
