Porting n63 exhaust turbo manifolds.

Has anybody ever ported the stock N63 exhaust manifolds?

It looks like it can easily be done, but is their any proven data claiming it is worth it? Porting the exhaust manifolds will make the turbos spool up quicker.
Just curious before I make an attempt to do it. I have a reputable shop that does ALL my porting needs for my racecar.
Wont be a challenge to have him do these. But the question is, Is it worth it?
