273 adjustable rockers on 360, very little oil to springs

The shims I'm referring to are around the shaft to align the rockers right to left. I didn't use the shims between the pedestals and the shaft because I didn't want them to affect the oiling hole on the pedestal, so I went with custom length pushrods instead. Also these shafts have the banana grooves and the additional hole for each rocker, so 8 oiling passages. Not sure if that changes anything.

I did check the cam bearings when I rebuilt the engine and the holes all lined up, and I cleaned up the all the valve-train and blasted them out with an air compressor. So there shouldn't be any restrictions.

It's possible these just don't pump a lot of oil to the valve and spring side. But per previous recommendations I'm going to check the ball and cup side and the the shaft for galling to be safe.
