Oil System and Valve Train Experts Please

There is a slight ticking to the rockers which I believe to be normal now.
Some say aftermarket rollers tend to be noisey. I set my pre-load to 0.021" (which includes 0.006" lash) using a dial.

What I don't find to be normal is the lack of oiling to the rocker arms.

There is nothing splashing out. The oil pressure reads 40 PSI (at the manifold sender port) at 2000 RPM.

Should I be seeing oil spraying from the rocker oiling holes? The engine
is cold, only running for about 2 minutes at this time. I'm a little concerned.

Here's a video of the rockers in action:

Additional info:

When I was setting my pre-load, I noticed the lifter seat did not move down.
I figured they were still pumped up. After rotating the engine by hand several
times, the lifter seat still remained solid. I was expecting the lifters to bleed
down?
After cycling the engine a few times. I checked the lash. I still could not
depress the lifter seat, however the rocker tips were tight on the valve stem
and the adjusting nuts and set screws were tight. I could not stick a 0.006"
feeler between the rocker tip and valve stem at TDC.

Thanks for your time.

The oiling holes should be aligned at the factory to spray oil on the fulcrum. Many if not most have this oiler built into the pushrod seat. During assembly of the rocker the oiler/seat may not be turned to align with its slot. This is actually fairly common, but I would never suspect all of them were assembled wrong. If you used heavy moly lube/paste on the pushrod or lifter you may have a temporary blockage.

When your lifters pump up after being run, you should not be able to depress the plunger of a standard hyd lifter by hand. They don't bleed down that fast.

They don't bleed down that fast.

I could swear that turning the motor by hand a few times, along with the
open pressure of the spring let the lifter bleed down enough to get some play
on the seat.

My main concern is the oiling.

If you were to quanitify the amount of oil squirting onto the fulcrum per
stroke at <=2000 RPM, would you say it's a drop/trickle , or would it
be more like a squirt/spray.

Again 40 PSI showing on a mechanical, capillary type gauge.
The engine is cold, less than 30 seconds run time.

Thanks for the reply.

Steady flow at 2000 rpm is typical. Its not going to put your eye out, but it will run onto the headers pretty fast. It does take a bit of time before they start oiling in many cases. Some oil straight away, but my flat tappet experience has been that it runs for a couple minutes and then the oil starts flowing. The type of lifter can also make a difference. A GM lifter has a different metering design than many aftermarket ones. I've only had one setup that oiled the rockers while prelubing before startup while turning the engine over by hand.

My suggestion is let it run for a couple of minutes. You should run oil over the rockers/springs before you start it up again and give it a chance to start flowing.

Awesome, that's pretty good info.

I primed the motor , and poured oil over both valve banks
before starting.

I'll give it a few minutes and keep an eye on things.

Thanks for your help.

UPDATE - WE HAVE OIL!

If you wait long enough, it will begin to pour out.

Almost a minute of continuous engine run time (even after priming the motor).

Weird...but I'm happy to see that blood flowing finally.

Thanks for your help again!

Glad you're up and running.
