A tubular mount system for a rocker arm which includes a rigid clamp at the base of the engine head is disclosed. Included is a pedestal mount/adjuster with external threads engageable with internal threads of a trunnion assembly cooperatively associated with a rocker arm whereby the rocker arm can be raised or lowered by turning the pedestal mount/adjuster, rotatably received by a rocker stud. This eliminates the need for an adjuster stud and nut on the rocker arm and a pillow block to hold the device together.
