There is a big header option that works with torsion bars. Bob Mazzolini Pro Part headers. They are step headers, 2 to 2 and 1/8" with 3.5" collectors. They are also partial fenderwell headers. Two tubes on the drivers side and on tube on the passenger side run through the wheelwells. The collectors are under the car next to the trans. I have them on my 440 Gold Duster and I even have factory power steering. On top of all that, they don't trap the starter like other long tube headers do.
