found that one of the blocks has grey crap in the base of each depression in the base. It also has a couple of gouges that look like the previous owner stabbed it with a flathead screwdriver... WTF.

Welcome to the wonderful world of Aluminum/Copper hybrid blocks. The reason you cannot open it is because it has oxidized and because there's a black washer cardboard like that goes all around the edges of the aluminum to seal the block from leaks... makes a tight hold.
The grey crap you see is bits and pieces of aluminum from the top portion that is degrading and falling apart. The marks that look like a flat head screwdriver hit it are mearly marks left over by the previous owner who knew water was eating away at the block.
I suggest you return it and get your money back. The person who had it before must not have used Hydrx with the blocks and just straight water. And the fact that the person tried to open up the block shows that he knew about the issues before selling you the blocks.
they will eventually spring a leak and ruin your rig.
Been there done that with that exact same block.
