Think about logic and basic statistics. You can't compare various engines that have significant differences between them. If your saying you have taken the same motor with various installed camshaft settings, advanced and retarded and under the exact same operating conditions and ambient conditions they operated at different temps., then I'd say that's interesting. Otherwise it's not good data as it relates to not degreeing a cam and degreeing a cam.
You have to remember, cruising around is not going to force the engine into producing a lot of heat. If a cooling system is designed to control the waste heat produced by a 300 HP motor, why in heavens name should it have a problem cooling to a setpoint on the thermostat when cruising around only generating maybe 40 HP? Even if there were, some small minute additional amount of heat by being 2 degrees off on camshaft timing, the headroom that is built into the cooling system would easily dissipate it.
