egr? to eddy rpm intake match up on a LA318?

i have a LA 318 im building up and i just put my heads on it. But when i went to mock up the intake I have a little issue. Check out the pictures. Im guessing he port in the center of the intakes, on the head is egr? Well my intake has provisions for the small rectangular port. but the half round port around it sticks out?? Am i in need of a different intake? and if so, what kind? because i was told the intake i have is the EGR kind. now i could be wrong and its something completely different like water transfer. But thats why im here asking you guys!

thanks
