Headers For "A" B-Body W/360

I know there's quite a few here who are experienced with 78-79 Magnums (and late B-bodies in general) My son has a 78 Magnum with a 360, which already has 2-1/4" duals but he wants some headers that fit good. Anyone have good recommendations for brands that fit the LA engine late B's? Summit, Patriot, Doug's etc. More affordable the better in this case. Thanks
