I often run mine on a test stand to get the engine dialed in on the mixtures and verify that it runs well. Maybe half a tank to a tank of fuel, with no sustained high rpms. Then I mount it on the airplane and fly it. Flying is the best way to load and unload the engine, heat cycle it, and break it in. No hovering for the first several tanks in order to help keep the engine cool.
