EGR Port Connectivity

Should all six EGR ports have a clear passage between them? I managed to clear a straight line path between each of the back four. Not sure about the front two and how they are "connected" to the others.

So the front two are NOT connected to the back four? And the front two are connected to each other in a straight line. Is that correct? I sprayed carb cleaner in the front ones and EGR valve port and it didn't really drain out so I'm wondering if I still have a blockage somewhere.
