Yes, but its all relative. FYI: The cam timing does not stay static when the engine is running. At low RPM or idle when the chains have the least tension, the cam timing becomes a bit advanced and as RPM's increase the timing gradually retards a bit. Thus the 'timing range' and the suggestion to time in the middle. As long as both chains were tensioned equally and cams timed equally, then as the chains/gears break-in the timing on both cams will equally change. The chains/gears will wear, but since timing is not static, you really cant compensate for it and it wont be noticible by seat of the pants for sure, possibly with a dial gauge. Don't loose sleep over it.

BTW: When you timed the cams, did you notice for each revolution the timing changed a bit, then after a few more revs its back to where you initally measured it? This is due to the minute differences in the chain links and gears. So, if you really want to get picky with the cam timing, mark a link and corresponding sprocket tooth and measure/set cam timing only when these meet....for the obsessive complusive. The whole point is cam timing is not a perfect science. Tension the chains equally, set the cams as equally as you can, button it up and enjoy.
