Is there an actual procedure on what should be adjusted first to last?

I adjusted my idle speed air mixture screws but the timing still flucuates. When I was setting my timing to 8 degrees as per factory setting with the vaccum hose off the distributor my timing mark on the crank periodically flucuates not staying in one steady rythm? Does anyone know what causes that? I did set my dwell to 30 and they are saying anywhere between 29 to 31 is the factory setting. Just fired up my brand new rebuilt 1970 350LT-1, and after breaking in the cam for a 30 min period, I changed the oil readjusted all my valves and fired it back up to set the timing, dwell, and carb.
