Not sure about the vac-bagging and resin infusion side of things, but I've used a similar technique with wet lay carbon around a foam buck. You'll need some barrier between the carbon and the foam otherwise the foam will absorb the resin. Packing tape makes a good barrier and has the advantage that it works as a release agent so you can remove the foam by just cutting it up and then removing the tape without having to dissolve out the foam.

Actually wouldn't a properly smooth intake be undesirable, in terms of having turbulence to help even out the fuel-air mix throughout each cylinderfull?

Polished smooth, yes. But an 80 grit finish is enough to create a decent boundary flow, it doesn't need to resemble a relief map of the Andes.
