Turning it over a lot by the crankshaft bolt is a good idea. Then, before fully starting it, I would hold down the "STOP" valve while cranking it with the starter. Do this until you see the oil pressure build up to "3", then release the STOP valve and let her fully fire up. If you're starting on the stand without an oil pressure gauge, maybe do this crank-stop procedure for about a minute or so. It'll be tough on your starter, but will allow oil to circulate and pressurize.
