I have my IB torn down and see cracks between the cylinders. Should I scrap the block and look for a replacement, or should it be ok to use as it looks like the cracks would be sealed by the head gasket?
Opinions?

Run it. Head gasket will seal it off. 95% of the B blocks out there are cracked in the same place

Don hit the nail on the head. Most B's have those cracks.

Cracks at the top are fine.
 
Cracks at the bottom mean new block.
