Not bending pushrods just the rockers don't sit right on the valves because of the angles just wondering if stud girdles would fix it or not (has anybody had to do this ) couldn't even run the dart guides they were just too week and broke right away

or if you dont want to use the adjustable guide plated you may want to look into a set of td shaft style rockers..you can shim the side to side clearance so the rocker is square on the valve stem..

The failure is always like the middle shot it always the end off we are using gm guide plates now they are much better but the problem I definitely geometry pushrods length is correct running 1.7 and 1.8 rockers was thinking that the solid shaft rocker might be the only way to go the pushrods are strong but there is obviously some side pressure in order to break the guide plates ????
