Not FE but still Ford --- 351 Cleveland question

[FERoadster]

On the old FEForum I've got 351C parts for sale but the intake I'm selling for the local scrap yard is listed as a Holley Street Dominator for a 351C with 2bbl heads
What is the difference from a 351C with 2bbl vs 4bbl heads? Are they interchangeable?
A picture of the underside of the intake. Do the oval ports mean this would not match 351C 4bbl heads?

Two barrel and four barrel Cleveland heads have different ports sizes. The four barrel is much larger.

The heads are classified as "2V" and "4V", not necessarily 2 bbl/4bbl.  You can run a 2V intake on a 4V head, the ports are just way small compared.
