Have the rest of the modifications required for the conversion to full flow already been done? IIRC, the right most port in your picture is part of it.

tubman is correct! you must be 100% sure there is no restriction between the two unused holes (plugs)
someone has done some modifications to facilitate a 80% fullflow filter. part of this proceedure is to put an internal plug in the oil gallery. the internal plug goes between the fitting with the copper tube and the innermost brass plug
if the internal plug is in there and you run the engine it will be destroyed!
