On the exhaust side, the routine follows the same as the intake. We turned the engine over until the intake pushrods moved all the way up. We rotated the engine past maximum lift, about two-thirds of the way back down to get the lifters on the base circle of the cam. We then rotated the exhaust pushrod as we tightened the polylock. After getting zero lash, we turned the polylock a half-turn clockwise and then tightened the set screw. The same goes for the remaining exhaust side rockers.
