That article is about breaking in a new or freshly rebuilt engine to seal the rings correctly. If you are just replacing the cam and lifters you should follow the breakin procedure that comes with the cam. Mine was to apply lots of the cam lube that came in the kit to both the lifters and cam lobes. You must get the engine setup so it will start right away. I poured a couple ounces of gas right down into the carb and it fired right up. Then keep the RPMs up over 2000 and blip it up to 2500-3000 or so every so often. Watch the oil pressure - it should stay at 60 psi. Keep this up for 20 minutes. Change the oil and filter and you should be good to go. Of course I haven't driven mine more than 10 miles since then, but I'm crossing my fingers
