This sounds strange. I have not run the block numbers to see what engine you have, so I am assuming it is a 235, baed on the head numbers. You should have a line coming out of the block from in between the two center lifters that connects to the center connector for the rocker shaft. Oil should be pumped through this line and supply the front and rear sections of the rocker shaft. The inside of the shaft should be clean and oil should come out through a hole in each rocker. You need t get a shop manual and see where things connect and what you are missing.
