Should i be concerned? Rocker oiling deficit

No leaky shafts here.
I got the #2 intake rocker to line up a touch better.
When putting it back together after visual inspection, i tapped shaft towards rear of car before tightening. A bit more lined up.
I’ll test mañana.
I like the idea l of cutting a groove in shaft towards oiling hole to help.
i need to check how oil is getting to the adjuster. If im modifying, might be a good time for a hole drilled in rocker like the gold one pictured above.

I think you need to inspect the rockers more carefully.
The holes from the rocker ID to the adjuster screw are there(or should be), but you’ll need to remove the rocker from the shaft to see it.

We use a clear valve cover on the dyno to watch for oiling problems. Aftermarket valve trains on BB Mopar engines can be tricky. Many aftermarket parts have problems when they are mated with other aftermarket parts so you have to verify that everything is working properly. A clear valve cover makes it easy to see what is going on. Here is a short video:
I spoke with Mike at B3 racing engines in PA (@RustyRatRod) a real nice fellow, very generous with his time in explaining things. I hope to do some business with him in the future.
Ill be taking the assembly off again and checking the hole that oils the adjuster and I am thinking of trying to make a notch in the shaft to allow the hole that oils the top of the rocker to get more oil (we are talking about the #2 intake rocker)
Mike also explained with these non bushed rockers you can't run high spring pressures so be careful to short shift and not get into valve float or other bad things happen.
Ill keep you updated to my progress. In the long run I think Ill build a 400 block I have around. 440 source will get a call to see if their prices are jacked.

Yeah, the rocker arm problems on BB Mopar engines multiply as the power level goes up! I learned that the hard way on multiple engines! The original design works for low RPM truck engines. The rotating oil switch in the cam shaft is a clever design but it has an upper limit. The shaft with a bunch of holes that line up with other holes in timed events also is clever, but has limitations. The whole system has to be redesigned as power levels go up.
And of course, modern hot rod parts are notorious for low quality. The quality of hot rod parts is now the lowest I've ever seen in my career. We see defective parts come into the shop on a daily basis now. Everything has to be double or triple checked before it goes on the engine.
