273 adjustable rockers on 360, very little oil to springs

Finished putting 273 rockers on my LA 360 this spring and pulled off the oil cap a few days ago and while running there was very little oil coming out of the top hole of the rocker. Even when I revved it up I could see it pulsing but just a very slight trickle at best. I shut it off and looked at the springs and they looked almost dry. Everything seems fine, but I remember the old stamped rockers throwing oil everywhere.

Is this normal or a problem? I've heard the springs need oil to stay cool and don't want to hurt my new pushrods or valves.

Running 5-30 synthetic oil (hot), good oil pressure
Previous stamped rockers threw tons of oil
273 rockers with stock banana shafts, cleaned up with new adjusters
Shafts oriented correctly
At most 2 thin shims per rocker used to center rocker on valve
Car gets a lot of spirited driving through mountain roads hitting 6k often

If needed I could open up the oil feed hole on the bottom of the shaft and better align the holes for the rocker arms. I just want to see if this is necessary before pulling everything apart.
the notch at end of shaft, goes to the front on drivers side and to rear on passenger side. this is from service book. also, notch goes down.
