Question Trying to save a '64 GTO block

I have three blocks that look like they have been sleeved. Protrusions at the bottom of the case. One is a 69 400 block, two are 64 blocks, one of which codes out to a 64 4 speed GTO block.

I have a fourth block, a 66 421, that has the cylinders even with the bottom of the case.

The questions are, 1) Has anyone heard of sleeving an entire block? 2) If the block has been sleeved, can it be re-sleeved back to standard bore? The 64 GTO block is already 0.030 over.
