They can and have been made to work on a type 1, by heating the intake and tuning the jetting and accel pump.
But as for you question... the only one I can remember seeing on a type 3....the carb was not in the exact center....meaning the manifold parts were different from right to left.
Check the tube manifolds for differences in length and offset.
edit....
Empi kits are not well known for how well they fit. It is not unusual to have to fix/modify the less expensive parts to get them to work.
