Any good body sealer would work fine.

When I did the body-off-frame resto on both my '55 Fairlane and my '55 Courier, I got a sheet of foam gasket material from local auto store and cut-out gaskets using the bottom flange of those air-intake elbows as a pattern. Then I cut out two more gaskets exactly same for the ducts on the inner fender apron.
After assembling the painted elbows to the painted firewall with the gaskets sandwiched between, I then got a glob of "Duxseal" and smashed a gob over and around the four mounting bolts that hold the elbows to the firewall so water can't get between the bottom of the bolt-head and elbow flange and run down inside the car. You could also use a bathtub caulk or "Vulcan" caulk instead of "Duxseal", but that would be real messy and ugly.

A 2-component body sealer. It's pretty much permanent, and impervious to everything. 3M, Fuzor, Norton, PlioGrip, they are all pretty much the same, all cost the same, (somewhat pricey) but they work equally well. Meaning great. Norton is my personal go to. It should be used on bare metal for the best results, and can be painted over with anything at all.
Those ducts have to be sealed very good, as any water you may drive over, will get drawn into the heater system, and fog up the windows.
