Hp manifolds on New Yorker

Might be other posts on this but im new here. Anyways i have a 67 New yorker with a 440. And i scooped up some really nice 69 date coded Bbody HP manifolds really cheap. Anyways will these things fit at all. They kinda just fell in my lap this weekend while i was outta town and huntin down Mopar parts! And i love the look of em and im gonna put dual exhaust on it anyways since the original muffler finally gave up!
