Fender well headers (small block)---For my survivor '64 Valiant race/street car

Hi all. I just rescued an untouched '64 Valiant that was special ordered for street/strip racing. It was retired (parked) in '71 and has not been driven since. I am trying to get it back to driving condition. The headers were rusted gone. I believe that they were Doug Thorley because of a sticker in the window, but any brand would probably fit. Thanks.
