I'm (re)assembling roller lifers in SB Magnum, and want to be sure I'm doing this correctly. Obviously, the hole in side of lifter barrel goes face up, aligning with the oil feed passage in block. But what about the small hole in the cap which allows oil to the pushrod? Is there a need to orient this hole with respect to the lifer. It doesn't appear to matter, but I would rather ask than pull the engine apart and fix later. Thanks...
