Remember that Weber carbs have demands very unique from a conventional 
four-barrel setup.   Among other things, the camshaft needs to be optimized to 
have enough of a vacuum signal for each carb throat to work properly.   Weber 
cams feature unusually wide lobe separation (115 degrees for example) to 
accomodate this.

If you have a typical four-barrel rumpity-rump camshaft with a tight lobe 
center (my Pantera cam is 108 degrees I think, my Cobra is 108 and my Mustang 
is 109), your Webers probably won't be happy.   If you intend to keep the 
Webers, you should install a Weber-friendly cam while the motor is out.   
Here's one example of a hydraulic roller, made by Comp Cams for Inglese:
