Headers for a small block dart with power steering?

Hey there, I have a 1973 dart sport H code car. The 340 is long gone, but it has a 1971 360 in it. I am thinking of putting some headers on it, but I have power steering. While watching an episode of Roadkill, they mention they had to custom fit a set of headers because they also had power steering. I have done some looking online, but can't seem to find any that will fit without custom fabrication. My question is, is there an after market set of headers that will fit a 1973 dodge dart sport, with power steering? Thanks.
