Oh yes do work to the heads, and unless your ports have been hogged out you'll be way ahead, as port velocity and flow will be better in low lifts with the 1.88's and on the street they are pretty much unmatched, velocity is king. As for the ports they are similar on all sbd heads, just gasket match and bowl blend them and your done, with a good VJ. All the rest looks very good for street.
