Short Rams would have 3505s carbs so they aren't original to the intakes. 3816 puts those in the 1963/64 era but I don't see anything in a Mopar application for those, likely another make application or they might be a marine or industrial application, recheck the numbers or better yet, post some pics.
Edit: To your edit, 3861 makes more sense. Those are listed as 1965 Street Hemi dual 4 (and of course we all know there were no 1965 Street Hemi cars built). So they are likely an early over the counter piece used as a replacment for the original 3505s carbs that you didn't get. Still like to see some pics of them.
