Grease is to prevent wear. During break in, you want to wear the gears into each other, not to prevent it. An abrasive compound is usually used for this. I would not grease the gears if the intent is to wear them in. However, once worn in, I would recommend always keeping the gears greased to prevent further wear.

For 968, we have not had to do any specific break-in procedure on our gearboxes in recent years, since we add a couple thousandths extra center-to-center distance.
