There really is very little emperical data (dyno runs) to differentiate the various combinations of cams, sprockets, carbs and ignition settings. However, thanks to people like Tim the JHPS board contains a lot of information to help people piece together some ideas. Others have been kind enough to share their data so we can examine the dubious 'should' and 'ought to' statments that are out there.
The data out there suggests the dual 104 cam combo on 104MOP sprockets produces extremely 'peaky' results (http://www.lotusbits.com) with not much usable power in the everyday driving range. One could argue shifting to 115/115 timing would produce more low-end torque and drivability. Get a set of 104MOP sprockets, then find us a dyno shop and let us know!
Instead of dropping $1500.00 on a set of Dellortos, how about putting a 107cam on that exhaust and using those 104MOP 'green dot' sprockets. My personal experience with various combinations suggests it is hard to beat the Excel SE 104/107 set-up for power and drivability.
