Celicamad 85,
Just to reference you post !

ive heard everything on these forums now...
* stock air filters are better than ones which flow more air
* 2.5 inch exhaust is 'better' than a 3 inch exhaust
* you dont need to port and polish an engine just cos all the racing and performance guys do it for extra power, they dont know what they're talking about
* oh and stick a 1g-gte in it, whatever 'it' is, thats really the only 'mod' thats recommended

Thats because people come here to discuss idea's and opinions. They key to the whole experience being worthwhile is actually listing to what other people suggest and the reserch all the options and make your own final decision. You have to be prepared to take the advice of those people who know more than you do 
Back to the topic tho. On the Polishing of exhaust ports I cannot add worthwhile comment. It is however not uncommon to mirror polish the bottom of the valves to deter carbon buildup. Yes it will still hold carbon but in theory not as much and definatly not as quickly. If the anchor point is only small it will support a smaller amount of carbon against the flow of air thru the head. The better (read Bigger) grip the carbon has the more it can resist the head flow to be blown/sucked into the exhaust.
As for the Boundy Layer this is indeed a consideration for Both EFI and carby vehicles so whilst the benifit and requirement to maintain particle suspension can be debated it doe not change the fact that the smaller boundy layer (read thinner) is a good thing.
