Carburetor inlet shape

Carburetor inlet shape

Carburetor inlet shape

(OP)
I am designing a 4 barrel carburetor (similar to a Holley Dominator) and would appriciate some help from someone that knows about the design of air inlet shapes.

The engine vacuum at full speed open throttle = .5 hg water

The fixed parameters of the inlet horn are:
Length = 1.25 inches
Small diameter = 1.90 inches
Large diameter =  2.75 inches (larger if they overlap)

The values I need guidance on are:

Angle at opening: ?
Shape: constant radius (r), conic (rho?), ellipse (angle)?
