Offenhauser Intake Manifold

Do the intake to head bolts take a 1/2" wrench or a 9/16" wrench???

Lots of running up and down stairs but my wife said I can afford to loose some weight. LOL. They measure 1/2 and the number on the intake is 2465726 if that can be crossed reference with something. Also I could not find a number on the heads.
