I would say there are other good methods of breakin , but as in the vid , during the idle process I do, the engine does start to loosen up some, the idle starts coming up and the temps usualy come down some during idle, so the engine is not just sitting there pounding,it is starting to breakin a little . I always preheat to 210 deg and with wrapping the head of the engine I can keep a 215 - 220 deg engine and still running rich to help in flushing engine breakin particals out. Hope this helps, Dave
