What Headers Needed?

Ok, the 72 Dart I just got had Hooker Long Tube Headers and glass packs bolted right on. Well went to the muffler shop today and got the glass packs removed and had flow master in it's place. Now since I can now hear with the glass packs out, the headers have a big crack on the rear outlet. The muffler guy said it can be repaired but would need to be taken out. These headers hang low and hit sometimes, thus the crack. I would like to put on new headers that can be installed easily and not hang so low. Car has 318, and power steering. Want to stay as cheap as possible but still be tucked up and not involve a hard install. Previous owner said he had to remove the engine to install the current headers. Definitely something I don't want to do.

Thanks,
