Reccomendations for valve adjustment.

Will be taking my truck in to get the valves done and am looking for numbers for intake and exhaust that would might give me a little more mileage and run a bit quieter.

Cummins spec is .010" on the intake, and .020" on the exhaust. States on the data plate on the side of the timing case.

I did mine a .08/.18

I think that's where most people do it. A little tighter won't hurt anything.
