273 rocker arm adjustment

Ok I'm following all that except, my shafts only have 1 hole per rocker and without banana groove.

I am going to solder that one hole shut, and add two holes, locations transferred from the two holes in the rocker arm on base circle of cam

So I won't have an hole where the bottom of rocker shows all the galling? How does that area that is taking all the load get oil.

I understand how the rocker arm adjuster tip and valve tip get oil now.

But how do we oil the very bottom of the rocker where the galling is happening? I will end up with two new holes in the rocker, which one do I add bana a grooves too.?
