  1. Pushrod Geometry

    GN7 On the Dyno
    SF is mid lift 90* rocker pivot/ valve stem. This does not necessarily put rocker tip on the center of the valve. I was taught the center of tip, smallest pattern years ago. I see the validity of both methods. Discuss away. Wags

I got a new rocker but when I go to tighten it, it still is able to slide because of the groove in the guide. Can anyone point me in the right...
