If your car is a 1750, the venturis should be around 32-34mm depending on tune. Main jets are roughly 4xVenturi size (for 32mm venturi use 130-135 main jet) and idle jet can be 50F8 for most Weber applications. F16 or F9 are good emulsion tubes, part-throttle acceleration will determine best one.
Pittatore (this is the right name) is a cam factory in Torino, making zillions of standard cams for the automotive industry, not necessarily specialized in hi-perf cams. Someone should measure your cams and determine the proper compression ratio needed, timing settings, valve/piston clearances etc.
