There are some tuners on NASIOC who say that headers are a waste of time, and others who swear by them. All I know is that the GT Spec IIs made a huge difference on Nick's car. Isn't his the first stock turbo STi to put down 300+ ft-lbs on Nate's dyno, when others with the same mods but no headers are around 270 - 280 ft-lbs. Dyno numbers don't lie (especially them new fangled road dynos).

I have a set on the way too, mine are sold in Japan as Tomei, slightly different design. It will be interesting to see the results.

BTW I read a while back on NASIOC the guys from gruppe-s found that coating/wrapping headers to retain the heat got back all the spool that they lost. Definately consider doing that!
