BB header help!

Hi guys. I am very new to the big block world so please bare with me . Only have a little slant 6 in my scamp until today. I just purchased a cool little 69 valiant with a 383 in it. Currently it has fenderwell headers. They are hooker super competiton, and they fit like crap. Dings all over them to fit. They hang down very low and tires hit the tubes at close to full lock. Any help on better headers would be greatly appreciated. I would prefer long tubes if possible.
Thanks
