I have my engine completely apart and all the bearings and seals out. I'm getting the bottom end powdercoated and the entire engine will be sandblasted, including the cylinder and head. My question is will the sand leave indentions in places like the sealing surface of the crank cases or anything like that? Will it damage anything? Also will it scratch up my cylinder and will it leave a dull finish?

If you have someone else do you, I think they can get away with a very fine sand media.
Vapor blasting is for sure a special cabinet. You definitely want to send your parts out for that.
After blasting, disassemble, then lightly blast just the few areas that the bolt heads covered up.
Soda blasting setup is cheap; just need a consistent compressor.
