A multiple cylinder internal combustion engine having a valvetrain with a camshaft disposed within an engine block and at least two valves operated by a common camshaft lobe includes a stationary shaft disposed generally parallel to the camshaft and a cam follower having a first end with an opening pivotally mounted on the stationary shaft, a second end adapted for coupling to at least two pushrods each associated with one of the at least two valves, and a roller mounted on a roller axle disposed generally between the first and second ends, the roller contacting the common camshaft lobe. The cam follower may include independently operable lash adjusters for pushrods driven by a common camshaft lobe.
