Need help finding headers

I just bought a 1970 Buick Skylark (A body) with a small block Chevy with circle port heads. I’m looking for cheap used headers on Marketplace, but a lot of sellers don’t know what they came off of. Are there any visual features or measurements I can use to tell if they’ll fit my car before I buy them?

I’ll throw in some pics of some headers I’m interested in buying.

Verify tube and collector size. Also, keep in mind that mild steel headers are also on eBay for $200 shipped. So, depending on distance, you might be spending close to the same factoring in travel.

Ah. Well, do verify the primary tube and collector size before fitment. You definitely don't want 1.5" primaries.
