Good point. No I would not, but someone replace them all after break-in, and it's the same.
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?
proper temeperature , quality fuel and not over reving a new engine are very key components to a proper break in
