I've seen a number of side-carbed conversions but honestly, everyone that I've talked to has had tuning issues with these set ups. Too rich. You see, the primary issues is the head. Honda calls it a 12 valve head but actually it's 16, including the little auxillary valve that opens in advance of the two primaries intake valves. What's more, the spark plug is pulled back away from the combustion camber just enough for the auxillary valve and the spark plug to work together in the little pre-combustion chamber before the main event. BTW, that's why it's so important to use specified spark plug for the cvcc engine because they are the correct length and temperature. Also know that the crown of the piston is shaped for the cvcc design only. Everything works together to create a lean burn. A dual carbed setup sounds cool and everything that goes with it. Just do a lot of research to find someone who's had great success. Chances are, they've gone with a different head.
What you are describing sounds like CVCC, but mine is d15a2, which I thought is non-CVCC. Or is it? Any way to determine that for sure? I know of CVCC concept and had problems with it back when I owned a Civic Shuttle/Wagovan back in Europe and tried to switch to a different carb and intake from another civic. Damn...
