Aero - yes, but mostly to speed up engine warm-up time. And in some cases (like extremely efficient hypermiling) to allow the engine to stay at a decent temperature.
Making the block more flush wouldn't hurt, but you might also want to leave some room behind it so the fan has a way to draw in fresh air if the temp rises.
