273 adjustable rockers on 360, very little oil to springs

This is GOOD observation.... if the OP has shims UNDER the shafts. The hole in the underside of each shaft at the 2nd hole from the left is larger, to allow full flow from the rocker stand. A small shim hole at that location would restrict flow. This area is the controlling flow restriction in the stock oiling path to the rockers (after the 'cam interruptor').

"At most 2 thin shims per rocker used to center rocker on valve."

I take it that he used the shims to move the rockers over the valve tips, I had to do the same I just installed the exact same setup on my motor do to the Harland Sharp rockers I had the geometry was so far off the only way to fix was to pull the heads and mill down the rocker pedestals, so I sold them. Hughes makes the correct geometry rockers, or so I am told they are also $800.00. Oh and the Harland Sharps I had were according to Harland Sharp were the 1st gen version rockers, I got used on Ebay...
