I'd use the dual plane, hands down. It will give you more power under the curve than the single plane. The single plane might peak a bit better (or not)- but you might be surprised at how well the RPM works.
I'm sure you know the deal w/the difference between the two designs; the RPM will have a broader powerband in almost every case where a streetable cam is used. This is especially true on a street driven vehicle where peak hp is not the most important thing. Not to mention the fact that you're running fuelie heads that don't have a very big intake port volume, even if ported. In my opinion there's no question as to which will work better on the street.
In the video comparison below, the heads are bigger than yours, as is the cam. Yet the results support my position, I believe. The results on your engine should be even more biased towards the dual plane.
