I would put it back together and give it no more thought if they are tight enough to please you. DF cranks are tough units, it's the rod bearings and aluminum rod that concerns me. The DF mains are an improvement over the F series IMHO. After honing, check for burrs on the port edges as they can rough up a new set of rings and piston if they have a burr or sharp 90 degree edge. A wide port can have a ring bulge out into it a tad and catch the sharp edge. A small riffler file will do the trick of knocking off the sharp edge. Good luck!
