The intermediate portion has upwardly extending side walls and end walls forming a large generally rectangular opening at the top edges thereof. The side walls have aligned holes carrying an axle on which is rotatably mounted a roller which contacts an overhead cam 22. One end portion of the rock arm has a downwardly-facing recess to engage an upper end of a lifter post 12. The other end portion of the rocker arm has a long, narrow web with downwardly-facing pads near the ends thereof and in predetermined, spaced relationship. The pads engage upper ends of two valve stems 16 for simultaneously operating valves to which the stems 16 are connected. |
