The text book for my engine rebuilding class said to do a number of full throttle-closed throttle cycles to seat the rings.

I also know a guy who hooked a power drill up to the oil pump and got the oil pressure up before starting it.

My theory is to do as many hot-cold cycles in a few miles as possible. This is cause the cylinder bore goes around and the piston goes up and down. The temperature cycling would temper and align the surface of the cylinder wall.
