Since I'm using Harland Sharp rocker arms, I need these to be oil-through pushrods.


The “traditional” method for top end oiling with HS rockers is thru the head/shaft.

With the standard ball type adjuster, there is no way to get the oil from the pushrod into the rocker body.
In that scenario, pushrod oiling would be dead headed at the adjuster.
