What's all this talk about shorter push rods being needed when the head is shaved? Does rocker arm geometry really change when the head is milled? I don't see how the the geometry actually changes because the adjustment seems, in effect, to lengthen or as needed when the head is shaved, reduce the length of the push rod. In effect the plane that the rocker works in stays the same and the movement (arc) in degrees would be the same. OK, enlighten me before you kill me if I am wrong.
