I’d say yes, it’s needed… to help seal (avoid bypass air) and to stop chaffing of the core on the housing.
Get some door/window seal from a box store… put a strip on either side to achieve the same seal/contact patch.
My core came with a pad already adhered to the top.

I seen aftermarket cores had weather stripping on 3 sides. Is that what you mean by pad?

Back when i first replaced mine i went with copper. It was not made like the oem one(less fins) and it failed a few years latter. Replaced it with the aluminum ones and it's been working great ever since. Get the one with out the swivel lines (they will leak). Also there is a thread here somewhere that has info on where to get the foam.
Is the foam a deal breaker ? I didnt replace mine when i swapped out to an aluminum one ....😪
