B or RB in A body

Hey Rusty, are you referring to the 78030 Hedman header at Summit? They are the same shape as the Summit brand, which are only $183. Only difference is in the flange thickness at 1/4", Hedmans are 5/16". Also wondering if you think the Hooker Super Competition headers would fit, as I have a set of those. THANKS

Not sure about the hookers, but the Hedmans have been documented in many builds. You can even see a build with them on bigblockdart.com And yes, I believe that is the right number. I have never seen anyone say the Summit headers fit.
