Don't make it too smooth. You want some turbulence so fuel doesn't stick to the walls. That said, you won't really gain anything doing this, but if you have the means and feel like doing it, it couldn't hurt.

If your talking about porting and polishing the openings in the manifold, it will get you nowhere. Getting down into the VDI manifold to port it all the way through would be nigh impossible.
