Valve check question

Hello everyone hope everybody had a good new year I was just wondering since these valves get tighter as it gets closer to valve adjustment interval, what is the loosest (if that's even a term) they can be while still being within spec I'm sorry I don't have a manual and I don't have the ability to print a copy right now any help would be fantastic. Thanks

I just checked mine at 37k. All were in spec, most at nominal, one or two at the high and low end of the tolerance zone.

Her's a link to the full service manual (hosted on my webhost)

I wouldnt worry to much about a valve that on the loose side of spec (even if it was one notch or so above the loose end of the spec) .... on the tight side, same thing.... but not more than one notch outside of spec. Especially not if its one valve on the whole cam.... not worth pulling a cam at that point.
