I wasn't concerned about the hole in the center of the lifter, but rather the hole which in the SIDE of the cap at top of the lifter. The pushrod oiling is supplied from feed in the center cavity of the lifter barrel, and then is passed thru the hole in the side of the cap and eventually out the top and up to the rockers. Folks are telling me I need not be concerned with the orientation of this cap, but as stated, I'm simply looking for confirmation of that.
