Oil pump seems fine, good pressure at the gallery along side the camshaft, and runs and sounds sweet, so I'm guessing most of it is fine, just the rocker shaft. Just couldn't figure out where the rocker supply comes from...

Have you had the rocker assembly loose? Not sure on the standards but a lot of engines that have shaft mount rockers the oil supply hole is only on one side of the shaft. If it was to get turned to where the hole is on top you wouldn"t get any oil. Also FE Ford engines used shaft mount rockers but the bolt where the oil supply is, was a special bolt. It looked like all the others in the assembly but it was turned down all the way to the bolt head to allow the oil to flow around it into the rocker shaft. I have seen several engines destroyed by people either putting the bolt in the wrong location or using a regular bolt in its place. That may be something to look at also.

Rocker shaft is fitted correctly, it gets its oil through a hole in the rear pedestal. There is a plug on the rear of the head that gives you access to the oil feed gallery up there, and there is no oil there either, just before the rocker shaft. It looks as if it gets a feed from the rear camshaft bearing, and if the plug there is removed, there is plenty of oil.
