Lynn,
A quick question!
The side inlets in the cast end-housing= s, have=20 a reducer ( reduction in inlet size) of approx 2mm ( all round) just aft= er=20 the opening. This reducer ( reduced area) carries through to the housing= =20 face where it changes to the face shape.
Does this reducer act as a choke of the= inlet=20 charge. I've had advice that it doesn't do anything but wonder why it's=20 there?
George ( down=20 under) 
Its just to account for production variations in the cas= tings.=20 There are no dowel pins to locate the intake manifold. Just the loose fit on= the=20 mounting studs.
 
So, there will never be a sharp corner sticking out into= the=20 flow from the manifold. An effective fix, but a poor solution power wise.=20
