2176 intake over 318 Head

Hello FABO
I finally got a chance to replace good old 2bbl with 4bbl intake. But when I dropped it it I learn that there is 2 open spaces as indicate in "RED ARROW". Is that normal or I had wrong intake? And are those plug holes "in Circle" are suppose to be perfect alignment or I have to make whatever adjustment? Any recommendations?

Thanks, FABO
