The 2.0 that I had a few years ago had very small ports. Maybe Edelbrock made them this way so that they could be ported, but they are much smaller than a standard oval port. I replaced the 2.0 with a Air Gap and those ports were much larger. There was quite a difference in performance with the manifold change.
