The oil tank on the engine supplies oil to a pump on the port side of the block. Remove the hose that exits from the pump and plug it. Plug all nipples on the pump.

After looking through some manuals, I see that on your engine, there should be an oil line from the pump on the engine to each cylinder separately. In that case, you should plug each line. You could snip the lines a couple of inches from each end and plug the short remaining pieces on the pump and intake manifold.
