Aye mate. Check if that rocker arm has any squirt holes that might be blocked/not drilled/angled properly. Check shaft/rocker clearance. might open up the small oiling hole on the shaft at that rocker arm, might take off the valve cover w it idling & see what you observe, it'd b messy but something might b apparent. Holler what it turns out being

Might consider banana grooves if it turns out to not be a blockage.

70 PSI is way too high, the pressure relief valve in the oil pump will open, or should, well before that. 20w60 is pretty thick, too thick for most cases, imo.
The factory minimum for warm idle oil pressure is something like 12 psi. Idle oiling requirements are fairly low, that might be why you aren't seeing oil at that rocker.
That all said, I think maybe your problem is the wrong shafts. I cannot remember if the W2 rockers have the oiling holes relocated for the offset that W2 rockers have. I suspect that is your problem.

from what you're seeing does it look like a smaller shank bolt at the bolt head or opening the shaft hole or?? will let it flow more

OK here we go... stock first.
Note the gap between the bolt and the head casting.

click edit then put a checkmark in the lower of the (3) boxes & click "change this post" then click on "browse" & select the pic out of your file where they are stored & click on that pic & it's address/name will load into the vacant white rectangular address bar. Not sure what your dimentions are but opening the shaft bolt hole dia or a smaller bolt just as long as the psi is contained from leaking out plus not restricted to flow into the shaft or at least the restriction opened up enough to get the flow you need.

I'm thinking if you drilled a hole down alongside the threads for the oil to get past the bolt threads but 1st not being familiar w W2's that is a pedestal just like LA's (it's shallow in the pic & hard to tell) & the only diff (as far as valvetrain is the offset rockers right? or are the stands offset also?). What I'm missing is what bolt do the stock w2's use that lets the oil flow past it? EDIT just saw your latest pics. I'd drill the notch in the W2's & unless I am missing something I think that'd b a simple fix. You'd lose a little bit of thread engagement but that wont hurt you. W care you could temporarily plug below your drilling to keep shavings out.
