1. A method, comprising:
adjusting a valve lift of a valve coupled to a cylinder via an adjusting camshaft on a first side of an activation lever and a camshaft on a second side of the activation lever, the adjusting camshaft comprising radially offset cams such that the valve lift of the valve of the cylinder is individually adjusted based on an engine load, the activation lever including an end in face-sharing contact with a second lever coupled to a valve stem of the valve;
wherein rotating the adjusting camshaft in a first direction increases an angular position of the activation lever and rotating the adjusting camshaft in a second direction decreases the angular position of the activation lever;
wherein the second direction is opposite the first direction; and
wherein rotating the adjusting camshaft in the second direction includes rotating the adjusting camshaft into a zero-lift position to deactivate the valve.
