Hopefully others will chime in with opinions but I think it is something that you need to do. Need to get that oil in all the passages in the block and head. I used an old distrib. with the guts removed except for the shaft. Stick it in the dist hole with the tab in the slot in the pump, put a drill on it and spin it until oil comes out of the oil feed tube on the rocker arm. Get that oil coming out of every place on the rocker arm it can come out of. Run it for a few minutes to get the air out of the system and filter.
