Break in procedure for rebuilt 5.9?

One school of thought is that if you drive it easy till it's broke in then jump on it later it could cause problems where the rings normally ride in the bores.
At higher RPM's the rods stretch a little and the rings travel beyond that broke in bore.

Another is that it should be broke in the way it's going to be driven.

I don't fully agree with either, but like to run em fairly easy with some short jump on it's here and there.
