I used to coat the bore with STP as well as the wrist pin. Not sure if that would be a good idea with today’s engines.
I used petroleum jelly on the wrist pins and 15W40 on the cylinders and plan to spin the engine with no spark plugs for 10 seconds to get oil pressure up, quickly install the plugs, open the petcock on the external tank, then start.Sure couldn't hurt... I used a 50/50 mix of STP and straight 40 weight oil on everything that moved: main bearings, rod bearings, cam bearings, rocker arms, cyl bores. Always figured it made things easier on a new motor the first time it fired up and didn't have oil pressure yet.
