If you are not honing the block .005" then you can go with a 3.898, standard bore piston. If your block is used, then you will need a hone, which would probablly require the .005" hone, thus the 3.905 piston. Most aftermarket pistons are set-up for the 6.125 rod, but you need to check with the manufacturer or vendor before making the final choice.
