your headers will need to be the header/downpipe that go to the head you are putting in the car... and if you plan on going turbo, you wont need header/downpipe, unless just for a temporary use... buy a cheap header until you turbo it. and if you want it to be worked on, pm blown99civicsi, (John) he just opened his shop not too long ago and invested tons of money in it... he is located in sarasota he can get you any part at a great price... plus he can give alot more details than i could about this swap. so if you have more questions ask him, im sure he would be more than happy to help you out, and trust him, he knows what he is talking about
