Does the smooth vs course finish apply to both dry and wet intakes?

Yes and no.

If you have the injectors down at the manifold face then you burr finish the manifold to about 3 inches or so.

There is still reversion in that case. And that’s EFI.

If you are using a system that puts fuel in at the top of the intake like a carb you burr finish all of it.
