Two barrel intake question

Does anybody maybe SlantsixDan or another member may beable to answer this question what year did mamopar start putting two barrel intakes on the slant six
The reason I'm asking when I first started my 62 valiant project the original motor had a two barrel carb but I didn't think anything of it I just thought maybe somebody upgraded the intake but the more I think about it with all the options my valiant had I was curious if in 62 they didn't offer a two barrel intake as a option
Thanks in advance
