Go fairly easy on it for 5-10,000 thousand miles(no sustained hard runs but easier short bursts more often), then work the heck out of it by towing something fairly heavy. Don't lug, don't rev too high, and don't stay at hi speed for too long. Also keep idling down to a bare minimum. Doing all of these things will seat rings into block better, and you'll have better power, less oil burning, and a more efficient longer lasting engine.
Worst thing you can do to the engine is babying it too much. Change oil at 2000 miles to get rid of contaminants from rebuild. Hope this helps.

There is no breakin on a Cummins. Cummins only recommends to take it easy for the first 100 miles to seat the rings. No ideling though, not over five minutes.
From service manual:
"Engine Run-in Without Dynamometer
On Highway applications
Operate the engine at 1500 to 1800 rpm in high gear for the first 80 to 160 km (50 to 100 mile) after rebuild.
Note: do not idle the engine for more than 5 minutes at any one time during the first 160km (100 mile) of operation."
