no oil to heads.

while running the gauge shows oil pressure. but there is no oil to the rockers. i removed the bolt where the oil comes in and while running no oil. it is dry. I did check the rocker shaft and oil holes are down and to the valve. I thought about head gasket. i ran a piece of wire from the head all way through the cam bushing after tearing it down checked both sides this way and actually saw the wire come throught the cam bushing. Same thing for the crank ran wire up to cam bushing and its clear.
