Go with the book when in dought!
As you wish, I merely said what "I" would do. I doubt .002" is gonna' make it any noisier, but it sure will make a difference if the exhaust valve starts losing clearance.
An exhaust valve can burn, whether it's air, or water cooled, AND, whether it started life in Germany, or Japan. There is NO lack of relevance.
The valves still cool by contact with the seat.
BTW, How many exhaust valves does a Fighter Jet have? None!
Judging by your response, I'm guessing the only work you did on fighter jets, was washing 'em, and maybe refueling.
And, if you can't spell models, or doubt, who the hell would let you work on ANYTHING!
