New to engine builds, question on boring block

I'm in the process of swapping out my cracked 53 block. Im picking up a bare block this weekend, and will be sending it straight to the machine shop.



My question is, what all should I tell the machinist to check?



What are the advantages/disadvantages to boring the block over say .10/.20? Truck is just a stock farm truck. Eventually plan on putting a small set of injectors and a turbo upgrade in the future.
