Road cranks are designed to sit further out from the BB shell, to accomodate the inner chainring/s.
You would need a smaller spindle than the Track Dura Ace cranks use.
Sheldon has a large database of chainlines with different cranks. I would work out which BB spindle length will give the road DA cranks a chainline of 42mm (most likely what your will be).
