No, you need to do your valve adjustment when the engine is HOT, because of the thermal properties of the aluminum head (expansion/contraction). Thus why you don’t find specs for COLD settings. (If you had a cast iron head, this wouldn’t apply.)

Exactly what did you do with your motor – complete rebuild? I would hook everything up, start it, run it for 3-5 minutes (to operating temp), then readjust your valves AND retorque the head. Always an anxious moment; helps to have a buddy near by for moral support…and a Guinness to quell the nerves!
