Rather than Port and Polish $500 you'd be just as good off taking a dump or taking out the spare wheel

[beeza]

If that was the case then why do so many people do it?

actually, theoretically and scientifically, there is only a real benefit from porting, there might be no real benefit from polishing depending on your setup. its good to have a slightly rough/textured surface so that when the fuel hits the head, it vapourises, which aids in complete combustion, which improves power. the rougher the head, the greater the surface area that can be used to vapourise fuel. altho too rough and it will hamper the flow of things like has been mentioned before.

Throttle bodies look good, sound great, are illegal in most states and need some serious tunning.

I have a feeling you are getting confused with INDIVIDUAL Throttle Bodies.

Yes ITB, otherwise we'd all be driving around with 'defective' stickers.
