Someone really good on a Bridgeport milling machine has machined out the Ford oval and then engraved the Ford logo on these heads. Could have started out as a pair of Fenton heads as the water neck appears to be somewhat wavy where the Fenton logo was cast.
The water temperature ports being perpendicular to the bottom side of the heads says Sharp Engineering to me. AFAIK Sharp was the only one that had them that way.
