One thing I like to do with all engines I rebuild. While on an engine stand, fill with oil. Then rotate the engine upside down and back up. This gives everything with a good coat of oil before starting. Just make sure everything up top is capped off or you will have a nice puddle on the floor.
If you worry about rust in a cylinder you can try some rust penetrating products in the cylinder then follow with oil.
Most assembled engines have enough lube to allow them to rotate. Once full, with the ignition off, rotate it till you get full oil pressure. Or you could use a preoiler shaft with a drill if you have one.
