As you HAVE cams from Alfar7 (here on the BB), why not ask him? The DCOM is somewhat different than the 40DCOE, both in the pump circuit and it's manner of transition from low to high speed circuits, being more an emission type Weber. My guess would be Richards jetting for the DCOE's and 2 L will be rich for the 1750 with DCOM's. However, it probably would do no harm, and might be a starting point. Best to check with your cam designer. I build and restore Webers, and while I've a good idea of reasonable set-up starting points, I ALWAYS defer to cam designers and engine builders for closer set-up starting points.
That was my main reason for posting Richard's suggestions here.
