The way I took it (-when Katy suggested annealing) was "Can this also be done on a graphite gasket?" -as in can this be done on this type gasket also.
I will tell you straight-up that the Model-A deck surface will NOT hold 75 lbs of torque without distorting. If the deck is distorted or the RA finish is not good enough, you will never get a Graphite gasket to seal (-new or used!!).

Testing should be done while doing machine work on the block and before any cleaning. This way you are assured there will be no drilling or machining after assembly with the consequent chips getting inside.
Threads should be chased with a tap, not a chaser. You CAN NOT get an accurate torque reading with rust and scale left in the threads.

Pete, since the Model-A block uses studs that are stationary, are you/we referring to rust inside the threads of the block affecting torque values??
