Intake manifold SB

Caferacerx makes a good point. My Eddy Performer has 1" X 1 7/8" intake ports while my LD340 has 1" X 2 3/16" intakes.
The Performer was bought used and it appears to have some work done on it, although I am not too sure about any rework on the intake ports. Wondering what the 318 head intake port has for its dimensions.
