6mm? specs are .18mm min, .23 max intake and .28mm min, .33mm max exhaust. That seems a little fishy in and of itself with a spec swing of .05mm.

I would ask them for the sheet as proof of a valve adjusment and if they "forgot" after you requested it they need to pull the cover and get the specs. If they hassle you I would tell them you are going to have them re-inspected (not adjusted) at an indie shop to ensure they are within tolerance.
