Only one valve was out of spec (exhaust valve 1).

I may have just had most of the intake valves adjust to the top of the limit and the exhaust valves adjusted to the bottom of the limit by the dealer at Inspection I, but the engine is somewhat smoother and slightly quieter now.
Those specs look really good! Exhaust valve 1 was an easy fix at .04mm increment too, put it right in the middle.
