Re: LG Header Install (TomsZ06)
What you will need are adapters that change the plug from a wide type gang plug to a square type which will connect to the rear sensor cable (the long one) and O2 sims for the plug in which is currently the pre cat sensor (which will become the aft cat sensor via the sim)

Re: LG Header Install (rutiger)
Everything should be in there. We supply a composite header gasket, but the GM gaskets from a 2000 C5 LS1, (NOT the Z06 ) will give you the longest life. You cannot use your Z06 gaskets because they are "Oval", and will not seal. If you get by a Chev dealer just ask for a 2000C5 exhaust manifold gasket set and you will be good to go.
Follow the included instructions, especially the part about the 02 sensors, and the adaptors.
Thanks and have fun.
Feel free to give us a call if you run into any problems.

Just to be helpful, the GM gaskets that you want are 12558573 and come in a package of 1, so you'll need to order two of that PN.
