1.
DETERMINE CORRECT STAND HEIGHT
Install the rocker stands on the cylinder head using the 7/16-14, 12 point attaching
bolts. The stands should be placed on the head so that the stamped letters face
the valve stem. Remove a rocker arm from one of the shafts and place that shaft
on a stand. Take the shaft height gage supplied with the kit and place it on the valve
stem as shown in Figure 1.
The gage should contact the top of the valve and the rocker shaft as shown in Figure 1.
If the gage contacts the shaft before touching the top of the valve stem, as shown
in Figure 2, remove a corresponding amount of material from the stud bosses on the
cylinder head. This will lower the rocker stand on the cylinder head.
