Which Chevy fenderwell headers suit (early) A-body best?

The port layout of a small chevy and a small mopar are very similar.
I think a big block mopar to small block mopar might be tougher.
I went to a car show this morning, saw a Studebaker Lark gasser with a bbc swapped in. I asked the owner which headers he used (if he remembered) and he said he thought they were early box Nova swap headers (no box novas, 62-67 with factory big blocks)
If the small blocks are shaped similar, I think they would be my choice for a modification attempt. Just get the uncoated version..... and have at it!
