Headers for the Duster

Recently I have been thinking about putting headers on the duster. I have a feeling that it is a pretty tight squeez though. I can't figure out how with the steering box and without having to cut anything how I could get some headers to tuck in there next to the 318....I am not sure what kind of headers to run brand nor finish so please if you have any ideas/suggestions or which headers to use, let me know! I currently have dual 2 1/2 inch flowmaster exhaust on it now with manifolds. I am not in a big rush nor have a whole lot of cash but if its what I want it will work itself out!

Thanks and I look forward to your insight!
