2 Barrel to 4 Barrel Question

I am putting a four barrel on my 72 D100. I removed the 2 barrel intake and when I dry fitted the 2176 manifold I noticed a void not covered at the exhaust crossover. Is this OK? I didn't notice it when the old intake was on, but it appears it did not cover it either. I think I'm okay. I just want to make sure.IMG_0171.JPGIMG_0172.JPG
