The end pivot valve train includes a cam follower forcing the cylinder valve, and a cam holder assembled onto an upper portion of the cylinder head and includes a receiving groove to receive the cam follower therein, wherein the cam holder has a protrusion configured and dimensioned to interfere with an upper surface of the cam follower when the cam follower rotates such that a longitudinal edge thereof moves up.
