If you think about this for a minute, you'll realize that there is one best cylinder out of 8, one worst cylinder out of 8 and the rest of them fall somewhere in between. There are just too many variables to contend with. The block deck height can vary from one corner to the other and be totally different from the other side, crank stroke can be off by several thousandths, rod lengths vary widely, piston compression heights are off a little one to the other, combustion chambers aren't even close to being the same volume in most cases, some valve seats are closer to the block deck than others, some valves are longer or shorter than others, ignition timing varies widely due to play in the distributor drive gears and timing chain, dual-plane intake manifolds aren't even close to the same configuration left bank to right bank, etc., etc., etc.
