ENd result was what was important, that the small differences in my deck height from piston to piston (due to factory allowed variance in the crank) are not significant enough to affect compression ratio.
I am not able to adjust at all with differing rod lengths since my rods were re-sized and all within .025mm of each other...

Chris,
It wouldn't effect your results in this case but be aware that stated compression ratios can be quite different than the actual (measured) ones.
