Default Do LS7 heads require special long tubes

I am having an LS7 built to put in my 2000 C5, I will be using C5 oil pan.
Does anyone know if it will require special LT headers to fit the heads or will any LT headers for a C5 work.
If it does require a LS7 specific header anyone know who might make them?

No. I don't think that you need a special header just because of the LS7 engine, however, you might want to go with a larger diameter tube such as 1-7/8". If you are going to buy a new set, I recommend American Racing Headers.

Well, the answer is usually YES. Most headers on the market do not have the flange port high enough to not block the top of the exhaust port. Even the L92s hit.
