340 Oil Priming Question First Start

this is far too much maths.

just pop the rockers off and throw them on the bench and then lean on the starter till the engine bay, hood, fenders and floor are sufficiently covered in oil and hope that the starter lead didn't melt the jacket off and light off all the slick stuff.

Yeah, take out the 2 bolts, start the drill/(turn the key) rotate crank at least 2 rotations, - 2 geysers to the ceiling, reinstall bolts, button it up.
No messing with rockers etc, jmo
