Coat all bearing surfaces in whatever assembly lube you can find at a parts store. It really doesn't matter.

Coat the cylinder walls in clean engine oil, not assembly lube.

Prime the engine by cranking it over without fuel/spark as described above till oil pressure is built

Run engine till it is up to operating temperature.

Take car out and drive it being sure to take it up to 3-4k RPM (not racing it, just slowly taking it up to that point) and once at those RPMs releasing the throttle fully and let the engine slow the car down. This builds vacuum in the cylinders and helps seat the rings against the cylinder walls.
