It cannot be the spacers, because the rocker is hitting the shaft pedestal BEFORE it is even lined up with the valve tip. The rocker needs to move TOWARDS the pedestal and nothing you can do with the spacers will help that. Grinding the inside of the pedestal is the way to correct this.
Makes sense. I will check everything once it's bolted down after I grind at the pedestal. The center of the rolers on that cylinder look like they are to the right. I will see if this bumps them to the left a little. Otherwise spacers will be next.
