Cryo treating blocks?

I'd definitely understand why it has benefits. I'm not 100% understanding in the science behind it but I can understand the basic concept of it. I'd think it would make the block considerably stronger for the long haul. Goal is to make it really resilient to the wear of the 600 hp area for a few years at least. Block prep (i.e. shaving casting flash, rounding hard edges etc.) will be done before it is sent our for cryo so I think that would also have benefits to have it strengthened in its prepped state
