I understand what porting is, im just curious as to know are there any proven gains from this. In the beginning i knew alot of people got it done but not so many now.

If there are gains, what are they, and what effects can you expect fro porting? Increase in psi? increase in sound? ect..

Any input is appreciated.

I just posted this question the other week. You probably wont get more than 3-4 hp so it is not worth the money. It is more of an art to properly port a supercharger, but porting and polishing your head should get you some pretty good gains.
