A valve control synchronizing apparatus for an internal combustion engine for controlling opening and closing operations of an engine valve includes a synchronizing pin assembly selectively transferring pivoting movement from one or both of first and second adjacent rocker arms to a central rocker arm. The synchronizing pin assembly is received in a bore defined through the central rocker arm and at least partially into each of the first and second rocker arms. The synchronizing pin assembly bridges between the first rocker arm and the central rocker arm to transfer pivoting movement of the first rocker arm to the central rocker arm and bridges between the second rocker arm and the central rocker arm to transfer pivoting movement from the second rocker arm to the central rocker arm.
