Edelbrocks are shorties and while they will give you an improvement over stock and are relatively cheap, if you want the most power get a set of long tubes. In California the ASMs aren't street legal, but it has been proved that they give the best results. They are ceramic coated too to keep heat down.
The Other Guys headers (TOGs) are mid-length and I have heard they are the best quality headers out there. They don't come ceramic coated but you can have them done for around $100.
If I had to choose, I'd get the TOGs even if I didn't have to worry about being emissions legal here in California because I would imagine the additional power you get from the ASMs is minimal.
Get in on a GP for the TOGs or ASMs if you want. Be warned though, they are a bit pricey.
You get what you pay for :read:
