I heard that there is less distortion using the process you described,
however most shops aren't yet equipped to do it. The shop I used does have
the machine as my friend and I found out. While most shops hone the
cylinders using a drill, this place has a computer controlled machine that
does it. The block is centered using the crank and cam journals so it hones
it exactly to the centerline and exactly perpendicular to the crank. Quite a
piece of equipment.
