Don't change it....
When I do Weber stuff we try to stick with the wider lobe centers and reduce the overlap.

The Weber style intakes open up a great deal of throttle area with small degrees of throttle movement - so you get a pretty big "lean hole" in the Air/Fuel demand curve. It's hard to fill that with fuel even with EFI mapping - you get an "on/off" switch effect.

The wider centerline cams will tend to soften the transient response there - you may not see it on a dyno but you will sure know it in the car. An added benefit for a road race style application is that - ASSUMING the same lobe - the wider centerline will give lower peak numbers but a wider, broader powerband.
(Please be aware that the above statement is a gross oversimplification and not gospel by a longshot - but is a valid generalization).
