Question, if you run a conventional Mopar solid or solid roller lifter with a hollow pushrod, will you still get any oil through the pushrods?

I've been fabricating bushing "sleeves" that i slip around the rocker hold down studs in the head where the oil channel passes up to the heads in order to reduce the amount of oil flow to the top as the stock system seems to push way too much oil up top that I'd rather have in the sump. I liken my simple mod to the guys back inthe day that use to machine the oil passages in the block to install holley fuel jets to reduce the volume,

I was always curious to know if any oil would reach the rocker through a hollow pushrod anyway. In either event it seems the rocker/pushrod ball/cup would get enough splash or vapor oiling in a conventional wet sump engine anyway. But with pushrod only (no shaft flow) oiling I could see that being a problem.
