Headers?

I’m wondering if these headers will fit my 225 /6 only information the seller has is he does not know for sure what these are off of. Any information would be greatly appreciated. I would like to put these on my 1972 Dart Swinger 225 /6 automatic. Along with an Aussie 4 barrel intake and an Edelbrock 4 barrel. Of course probably go dual exhaust
Thanks in advance.
