I enjoyed the photos posted and my 46 has the oil distribution plate and oil lines on the left side of the engine.
Though on the right side of the engine there is no rocker arm oil feed line coming through the engine block.
My engine has the oil feed line come up through a hole in between the valve lifters and there was no way to see were that oil line went to so no way to disconnect it to clean it out.
So I did the next best thing. I got a length of mechanics wire and reamed it out then I was able to use a brass welding rod to go deeper into the oil line. Then used some varnish covered bare copper wire to go deeper still.
Then with a new brass oil line fitting to connect the oil line to the rocker arm, for the hex on the old fitting was in very bad shape, I put the rocker arm assembly back on the engine.
We fired up the engine and the rockers were getting plenty of the oil now.
