I like to prime with a drill on a nice engine. If it’s and older hi miler just start it up. Yes charge batt and fill the float bowls first.

Cranking with coil wire off to get oil pressure is counter productive, just start it is a better idea. More RPM and quicker oil pressure.

Next time you have the intake off, pour 5 quarts of oil in the usual valve cover filler. It does not flood the lifter valley, it runs down in a few areas and the rest of it is dry. Along with most of the cam lobes.
