I was wondering if anyone has got a header port on a b16...does it show any gains from doing this and is it worth the money... Could it cause leaks and will my car be able to pass smog i get this done... Or is it better to buy my own kit and do it myself.., sorry for the questions I'm just interested

 

You mean...port-match? It's nothing noticeable. For the money, I would do other mods such as high-flow fuel pump, clutch, cams, etc.

 

On craigslt a guy does it for 30

 

save your $30. It's not worth the time. I did the same thing on my LS-t setup and didn't notice any improvement.

 

I think if I get it ported and some headers that I would notice some gains

 

You wont. theres a reason nobody does it, it does absolutely NOTHING.

I have seriously never heard of anyone doing that, ever and I talk to some of the best builders and shops ever that are known nationwide. So trust me.

 

You might get 1-2whpfrom the header (that's singular). I'd be willing to bet you wouldn't even get 1whp from port matching.
