well the only problem i can see with porting and polishing your intake side is that the air/fuel will not atomize (sp?) as good, tho it will improve flow. if you do decide to P&P, make sure the place has a flow bench.

you usually port both sides and polish the exhaust, the rough surface on the intake side creates turbulance in the incoming air which atomizes fuel better and decreases the chance of detonation, it will not however decrease your air flow, no point to polish it.
