In this case, it would be a mistake. Let the condition of the cylinders dictate the amount of overbore.
Looking at it from a power standpoint, the extra size is worth about 1 hp and 1 ft/lb torque per ci. So the difference between 0.030" and 0.060" is about 6.5 hp and the same amount of torque, all else being equal.
