Default Where to get afr 225's?

Where should I order my afr 225's from? Which company seems to have the best numbers in terms of ported 225's. I have an incon kit with a built bottom end and stock top end except for an ls6 intake. I ran a conservative 12#'s of boost with an 11.0-1 air-fuel ratio and made 580rwhp on pump gas(93 octane) on my 9:1 motor. I'm thinking with the ported afr 225's, 15#'s of boost, and a better cam(I have a zo6 cam now) I should make more like 700rwhp on pump gas. Let me know where to buy the heads and what you think my numbers would be.

You can purchase the heads direct from AFR. If not I'd advise purchasing from an authorized distributor. http://www.airflowresearch.com/dealer_listings.php

I knew I could purchase them from afr, but don't most shops get the heads and port them even further for more power or am I mistaken. I thought companies like thunder and such get the castings from afr and then port them. Please correct me if I'm wrong. If I'm correct, then who does the best porting job to maximize the power increase from the heads?

Most of the companys actually just sell the out-of-the-box heads that are already CNC ported by AFR. I would just start calling around to all the sponsors and find a shop with some in stock.
