There's a good article on Honda-life, comparing headers. Different headers will work better for you with different mods. I wouldn't stick a HyTech long primary on a car with no other mods. Likewise, I'd be hesitant to stick something cheap (no names :P ) on a car with lots of mods.

I was originally looking at getting a Type 1 Racing header for mine (with minor boltons, but more to follow) but they're hard to come by. The one distributor for North America was out last time I checked. I'm going with a JDM ITR 4-1 with 2.5" collector instead. They offer similar numbers (although a lot rougher band) and cost a couple hundred less.
