Good advice Jeff. That is exactly what I do. You don't want to overtighten especially if its a cork.
FYI, I broke out "How to rebuild small-block Ford Engines" by Tom Monroe
According to Tom, 1/4-20
oil pan bolts are torqued to 7-9 ft.lbs and 5/16-20 are torqued to 9-11 ft.lbs. He advises "Snug the pan bolts down several times because the cork gasket relaxes"
Valve covers are torqued to 3-5 ft.lbs.
Good Luck.
