Those 3 nuts should be on through bolts that run the full width of the stacks.
The plugs may need a sealing ring or o-ring.

The "plug" should unscrew from the block. Most of the time the through bolts have nuts on both ends. If you loosen a through bolt you can blow out the o-rings that seal between the sections.
