Yes - it is a standard machine shop operation . . . as long as the guys doing the work understand that these are BEARING SURFACES -- and they need to hone in a manner that provides a highly polished surface finish. Most guys are used to standard 'insert bearing' rods - they've never worked with full-floaters.
And Ron's idea of opening up the rods just a bit is a good idea - especially for high-performance usage where you want a lot of oil to flow. As we always said "loose is fast!".
Also, the way that you balance these early rods is NOT the same as modern engines - where you have a 'balancing pad' to remove material from. Many shops just grind the bottom of the rod - which weakens it. They need a special fixture that mounts the rod-cap in a lathe - where material is removed in the same manner that Ford did when they balanced sets of rods.
