If I were to put new heads on, but left the current intake manifold with 2 barrel carb, is that a bad move?

Vortec heads won’t work with a standard small block intake, they require a vortec intake.

As stated, no can do with Vortec heads. But you don't want the 2bbl. I don't know what the bad you've been hearing is, but a smaller cfm 4bbl will consume less fuel cruising and throw a heap more power to it when you mash it.
