Yes, there are several Cadillac intakes and port sizes, but most intake gasket sets available today have the later, larger ports.
The Caddy manifold I purchased came with a set of Studebaker steel shim intake gaskets which aligned well with the Caddy ports. I never yet installed it on an engine, so how well the cyl. head offset
and angle matches up remains to be determined. Might benefit from some port matching.
FWIW, the '52-54 Cadillac 331' were the smaller port 4-bbl. There is no great performance advantage to using one of these over the Stude 4-bbl.
The early Cadillac manifold appears to be a couple of inches higher than most Studebaker 4 barrel intakes. My plan was to have it aluminum coated as a poor man's "High Rise"
intake. Anyway at 50 bucks I had little to lose. And I'm not reporting that it 'Works Great!', only that it exists and -may- have some potential ...or at least -look- like it does.
Which for a lot of us is a sufficient excuse.
The port size increased in '55 when the Eldorado got the 2x4 intake, also offered on the '56 365". These are the taller intakes and carbs.
One Cadillac's major styling changes from '56 to '57 was a lowering of the hood line between the fenders. As a result the '57 2x4 intake manifold, air cleaners and even the carburetors are all SHORTER so that the assembled height would fit under a closed 1957 hood.
The 3x2-bbl intakes were for the '58-'59 and were also low-profile.
Thanks for this further information. I have a 3x2 and a couple of cast iron 2x4s but have never bothered to determine what years they are, also have a NOS Weiand 2x4. Started collecting these Caddy intakes for my Studebaker project, then came across a running '62 Cad 390 which is presently occupying an engine stand.
Finally retired this summer, and if I can ever get the 'honey do's' out of the way, will see if I can get around to playing with my accumulations of toys.
