For my piece of mind, after major engine work, especially working on the valve train, I like to rotate the crank 2 revolutions by hand, so each of the cyldrs go thru the 4 strokes without interferernce or resrictions. During assembly I make sure any anything that rotates is well lubricated. Pouring some oil over the rocker arms and shaft is not a bad idea. Instead of pulling the dizzy and priming the engine by the oil pump, you can pull the plugs and disable the ignition, and crank the engine over with the starter until you have oil pressure or witness oil at the rocker arm assembly.
