OOOOk, thanks everyone for your thought, even if some is saying the opposite than others.

If you had a new engine, would you tear it apart, put in used bearings, break it in, tear down, then put in the new bearings?
Good point. No I would not, but someone replace them all after break-in, and it's the same.

preheating your new engine and keeping it in a certain temperature range during break in is very important
when done properly there is no need to replace rod after a gallon of running as you have aleviated most of the stress on the internal componenets with the heat
i myself have incorporated the comp heat engine block heater into my break in program and am loving the results
Of course I'm gonna preheat it, but are you sayng that if I leave it runnin at high idle and quite rich for right lubrification, and if temps don't stay high I've to "help" them using heater while running?
