The valve gaps are specified for a cold engine, usually from an overnight cooldown. This should have the engine at ambient temperature. The catch is, ambient temperature changes with the seasons, time of day and what part of the country you live in. Here is the prerequisite from my valve gapping procedure regarding the temperature.
"2. The engine should be at the ambient temperature that the engine operates in during its use. Performing the gap adjustment in the range of 40 F to 90 F should be acceptable."
I have emailed you the valve gapping procedure. You should find the step-by-step instructions very helpful.
