leme know what you have to do when you put them in thanks
I installed a set on my Dart Sport a couple of years ago.
They have a link to the installation instructions on this page, about 1/2 way down on the right.

This was the easiest set of headers I ever installed. (Not counting the custom set I helped make for my old 2x3 frame ET bracket Challenger.) You don't need the 90* oil filter adapter, just a short filter, and the Mopar mini-starter is easy to get in & out with the TTI's.
The instructions do say that some of the steering linkage needs to be disconnected. Plan on it. But, I did my installation on an open trailer that sits a little high and is open in the center. This gave me a lot of room underneath to maneuver, as if the car was on a lift, and somehow I was able to get them in without disconnecting any steering parts! But the engine was raised off the mounts as far as it would go, rocked around and the steering was turned back & forth to find the most clearance during installation. But by disconnecting some links, it may be a little easier and reduce installation scratches.
The internal thermal barrier is a good idea because not only will it keep the heat from radiating, it helps protect the insides from rust, which prolongs life and maintains smooth, efficient exhaust flow. They also use thicker tubing than most other headers.
Remember to pay attention to your engine and trans mounts. OEM rubber deteriorates, gets soft and allows the engine & trans to sag/settle. That can cause interference problems. New OEM rubber, or better yet, poly mounts help restore proper orientation. I had to shim my trans mount a bit till I replaced the OEM rubber.
The 1 5/8"-1 3/4" step works well in a wide variety of applications, from street cars to race cars. I've gone 11.60's with my 3,530lb Stock class Dart and other have gone high 10's in similar, lighter cars!
They also clear all of the commonly available oil pans. Some headers will not clear the 8 qt. Milodon pans.
