273 rocker arms

[nm9stheham]

stockers have 2 oilers: one on top for spine and one at about -70 degrees for pushrod cup. Do 273 shafts address these holes with a timed (inline?) shaft oil port(s)? Cant see how they get oil on a smooth shaft with no grooves internally. I understand some later iron rockets dont have spine oilers.

The oil just works its way up there around the shaft and dribbles down.... it is only for the valve tip and that does not take much.
