Yellow circles indicate the pushrod holes and oblong oil drain cavities need to be tapped and plugged while the green shows the oil feed hole to the head that needs to be plugged and just on the side is a brass plug to the same oil feed passage which can be used with a cheap turbo oil feed line and brass fittings.
