I need exhaust manifold for 360 cheap or trade

I have headers that are all messed up and I wanna go back to manifolds but I don't know what to get I just know I have a 360 and I need some soon if I'm going to make it to the one car show I wanted this year. Anyway if anyone has what I need let me know , I can pay some or trade some easily removable parts off a dart swinger I have.
