Dear, Why are there 2 different diameters on the intake manifold while on the carburetor the 4 are the same ???

That intake manifold uses a Ford carburetor, not a Holley carburetor. The Ford is what the "industry" describes as a "spread bore" which has small primaries and large secondaries.

Generally speaking, you can not mix the application. You match the carburetor to the intake manifold. You have the wrong carburetor.
