Valve stem sweep starts just outboard of the centerline of the valve, then continues out from there to about 1/2 way to the outside edge of the valve (so 2/3 to 3/4 to the outside of the valve.
Thanks for the input, standing by...


If, when using a solid test lifter and the valve closed, the rocker to valve stem contact should start on the inboard side ( closest to the rocker shaft ). If the contact starts on the outboard side, the pushrods are too short. Ideally, you want the rocker to wipe equally on both side of the valve stem center line as the valve is lifted through the entire travel.




John, how does pushrod length affect rocker geometry/sweep pattern?
