Vent in baffle

You’re going to have to be more specific….fuel tank baffle? Engine baffles? Vent location? Part Numbers?
 
That's for the carb heater. Not needed if you don't have a carb.
Actually, it is used for cabin heat. But hey, not needed if you don’t have cabin heat. 🥶

Carb heat comes off a heat muff installed on an exhaust pipe.

Correct
Sourcing carb. heat from way at the back of the baffling will require a frustrating to execute and very (long) expensive piece of 2" scat hose.
 
That vent in the baffle intake ramp (#2 cylinder, left side) feeds both carb heat and cabin heat. Short run to carb heat works very well. Longer run to cabin heat valve on firewall works adequately. This heat muff is on the stock Vans (not Vetterman) crossover exhaust system.
Heat muff for carb/cabin heat pic 1. Vent is under the blue tape in pic 2 feeds heat muff. Short run from muff to carb box below alternator pic 3. Long run back to cabin heat pic 4.
