I don't see any real advantage to offsetting by .013, but that's the way the motor was when I bought the car. If the crank needs to be turned .010 or .020 under, might as well get the minuscule stroke advantage, too. (Note: in the Olds, most stock blocks have the pistons about .030 down in the hole, the offset will reduce the amount you have to deck the block)
