I would suggest to keep the original finish in any event. The chamfer required for the Mavic BB should not affect the installation of the Dura-ace cups as it only cuts a few threads off of the BB shell. Another alternative would be to 'shave' a few mm off of both sides. You could also simply keep the Mavic BB and verify if the taper of the axle will accept the Dura-ace. The Mavic BB's are fantastic quality and permit perfect chain alignment on any bike. I have a Team Miyata frame from 1982 that still has the 1983 Mavic SSC 1000 groupe on it.
