Holley 2-bbl on 273

The manifold on my 273 is a two barrel manifold. Will the Holley 2 barrel fit on that, or will I need an adapter for that carb on that manifold. Or will any 2-barrel fit any 2-barrel manifold. If it will fit, I will use the 350 Holley on the 2-barrel manifold on my engine now. And not have to find a 4-barrel manifold that fits my 64 273.
