1963 389 oil starvation

I have a 63 grand prix that's been sitting since 1970! It was parked then due to the rocker arms wearing through to end of the valve on 6 cylinders. The rocker studs are clogged. But it's actually the oil channel under the rocker studs that are clogged with oil sludge. My question is, has anyone ever removed the plugs on the sides of this channel and cleaned it out?
