NY300SD,

I use go-nogo gages. Intake: .003" go and .005" nogo. Exhaust: .013" go and .015" nogo. I always set them to the high side.

Always check clearance before looseniong the nuts. Some valves might not need adjustment. I had one 617 engine that after 25,000 miles, none of the valves needed adjustment.
