440 in a 71 Dart, Header question

Ok lets say you have a 71 Dart with a 440 and eddy aluminum heads. Who makes under chassis headers? and how big can you get them in. 1 3/4, 1 7/8, 2.0 ect. and if you can get them in 1 7/8 or bigger how hard is it to each the plugs? and what would be the cost on some of these headers? Has anyone here ever worked with a set of under chassis headers in a 70-72 440 Dart be for?

tti sells exactly what your lookin for 2 in for $691

bigblockdart.com has a lot of answers for headers in the tech section.

Or if your 440 is a mild build you could go to schmacher, easy to put in and don't capture nothing.http://www.engine-swaps.com/

I used the Schumacher headers and they fit nice. They are still good for a 12.00 second car.
