A rocker arm assembly includes a stamped body comprising elongate, spaced plates with a pushrod engaging block at one end and a valve stem engaging roller at the other. A stud mounting block is located at about the midpoint of the body between the two ends. The pushrod engagement block has an off-center rod engaging recess so that it can be reversed to alter the operating ratio of the arm. The block also has an internal network of bores to facilitate reception of lubricant from the pushrod to flow into and through the block. The stud mounting block is bored so as to provide for the body of the rocker arm to be pivotally mounted on the stud, thereby reducing friction and heat buildup during operation.
