I was the first person in the country maknig headers for these cars and I did exactly like Ray said, I bought BBK long tubes and cut them apart and rebuilt three of the four tubes on the drivers side.The passenger side fits fine, you just have to cap a port on it.
It realy was a pain in the azz, so I quite doing them.It was way more trouble than the measely couple hundred bucks I profited on them.I could have just raised the price but with the cost of the BBKs already and then the cost of getting them recoated and a new billet steering knuckle it was already pretty pricey.And then IF i had a problem with it not fitting just right my profit went out the window in shipping.
