I always adjust to the middle-to-high end of the spec. This ensures that they stay in spec until the next service. You really don't want tight valves....and yours are out of spec.

.0087" and the maximum .0114" for exhaust. I'd put them somewhere around 0.010 at least.

Two of your intakes are tight as well. Minimum spec is 0.006". max is 0.009. The should all be 0.008 or more IMO.
