if you bought it new it will have all you need. just make sure you use the supplied valley cover bolts the stockers are to long and will crack the manifold

being that your car is a 2000 I am gonna say that you don't have a ls6 manifold. you need to get the rear coolant block off plates and the front water bypass tube. not sure if the part number but if you go to your chevy dealer be sure to tell them it is for a ls6 motor. when I was looking for mine I had a hard time trying to explain to them that I needed these for a ls1.

You can get the coolant pipe and rear plugs from Texas Speed. I did this about 2 weeks ago. If you go to 90mm TB (Nick Williams), you will also need to do the TB Bypass modification. I used some fuel line (2 feet) and worm type hose clamps.

it will help alot, especially up high where it will breath way better thenthe stock
yea texas speed sells the coolant lines n block off plates pretty cheap, and they ship fast.
so get on it and get it installed, then let us know if you think it was worth it...bet you will!
