Are you on about a yb or cvh, i think cvh so you cant gain oil pressure from spinning the dizzy drive, i would just make sure the oil ways etc and everything is new and spotless, make sure bearings etc are all pre oiled on assembly and then once the engine is back in, spin it over without the plugs in to gain some oil pressure. I always make sure i use the cam lube supplied when starting a new engine with cam/lifters etc, never had any issues that way.
