Not necessarily; if the casting has sharp turns, sharp edges, casting defects and things like that I would imagine they slow the flow of air so removing those would increase the velocity or maybe better put there will be fewer obstacles to slow it down. Of course volume is removed in these localised areas but at this stage I'm not thinking of increasing the port sizes unless they are undersized at the moment.
The same design of stub stack I added to the carb intake was flow tested by David Vizard and it increased flow by 5.8%. It did this by having a large radius and eliminating the sharp edge. So that's the sort of thing maybe could be done inside the intake, giving the air an easier path.
I'm looking at a supercharger for another project but this one is staying original, or looking original.
