I've always brought my new engines up to temp, shut them off to completeley cool, then bring them up to temp again " at normal idle". I do this about 10 times before I repeat the process using a variable throtle. I've always had excellent results with this process on any ringed engine, glow or gas.
That should be fine, the reason I mentioned not to do any break in procedure is because I have seen more than one engine get cooked breaking it in on the ground by someone that did not know what they were doing. Seems like you have a handle on it.
