Going to take the engine out this weekend. Could I stay with Single port?

Single ports are nice (if keeping with the stock carb) because they are a little more "torquey" than a dual port.

But you have more options with a dual port, to make a better performer

Chris is right. What I have gathered from listening (reading) on the board, if you are going to stay stock keep the single port. If you are going to go higher performance (two carbs, cam etc, etc) them go with the dual port.

To me, the only reason to stick with a single port is if you are concerned about "correctness." Other than that, go with dual port.
