Will these pushrods work?

As to your question “where does the oil go when it dead ends in the rocker shaft” it doesn’t dead end. The rocker shaft has grooves cut in it that allow oil to lubricate the rockers and shafts. Also the “leaked” oil is “directed” to the tip of the rocker to cool the springs. If you are talking about the oil in the pushrod dead ending. It also weeps out between the rocker cup and pushrod.

Thank you, and yes I was referring to the pushrod where it dead ends to the rocker. I'm curious what the reasoning is for drilled pushrods if the motor still has oil galleys for rocker shaft oiling. That's why I thought there may be an oil pressure drop, with 16 new pathways for oil to leak . I guess the underside of the rockers will be well oiled.
