How is valve lash adjusted on ARDUN heads?

With a lock nut and an Allen adjuster on the rocker. Turning the adjuster clockwise runs the ball out toward the push rod. Steve sets the clearance with a feeler gauge, which he thinks is 12 thousandths on the exhaust for this engine, then snugs the lock nut.
