There have been a lot of posts on this subject. 
The best header really depends on how you plan to use the car. If the car is going to be driven on the street, you really want to focus on power under the curve and torque. The longer the header the better the torque.
You probably can't go wrong with ARH, Dynotech, LG, or Kooks. They all produce pretty similar results.
Take a look at this post.

We've had success with both ARH and LG. The fit and performance of both are great.
Did they say what primary and collector size they used? I didn't see the article, but it sounds like the plumbing was too large for a stock engine.
Check article in June Issue of Corvette Magazine, they basically say headers on an otherwise stock motor are a waste of money, I'm kind of up in the air myself, I'm not interested in 15 or 17HP gain at 6000rpm, I am looking for "seat of the pants " increase in performance.

If I remember right when I read about this header shootout, most of the top headers tested had almost identical performance results. It may have been one of the Corvette mags, or a Chevy mag. I'm still searching for article.

No one is talking about ceramic coating. Do most of you get coated headers? Anybody not get them then decide to get them coated? Where would you send them? I got LG LT pros and just got the stainless. When I have my h/c work done, I was thinking of pulling them off and having them coated. What's the thoughts about that?

Absolutely...and discuss the benefits of ceramic coating with them. Headers will produce a lot of heat on those long drives. The coating will help get that heat out (so the engine, drivetrain and your legs 
) don't absorb so much. After two years, mine still look brand new.
