Moves pushrod out .030 away and towards center of the pushrod tube. As we all know a problem exists when the pushrod is at it’s lowest and highest points, especially with high lift cams.  Thanks to a good idea from Gary Williams & Company, these rocker arm supports move the pushrods away, thus eliminating the normal rubbing contact points between the pushrod tube and the pushrod. When using roller rocker arms with 7 millimeter stem valves, the problem gets worse as the roller rocker tip tries to roll off the forward edge of the tip of the valve stem. This additional .030 inward motion helps to eliminate this problem also.
