New heads, new intake, new rockers, new pushrods - Very noisy valves and very little oil through pushrods

I'm kind of stuck here.
As my backwards head gasket ordeal continues, I got the new Edelbrock Performer RPM heads installed, new distributor, new intake. Old carb.
Pushrod length checked and is good.
Rockers are Crower stainless endurance rockers.
Cam is CompCams hydraulic roller.
Valves adjusted to zero+half turn, and then zero+3/4 turn.
Valves are very noisy, sounds like a diesel running.
Pulled valve covers, and surprised how dry they were.
Ran engine briefly with paper towels on top of rockers and got very little oil.
Pulled dist. and spun oil pump. 50PSI at back of block.
Pulled pushrod and put a borescoped down the hole, lifter seems to pump up but spinning the pump with a cordless drill for an entire minute i get just a few drops of oil out of the pushrods.

Any suggestions?
