Technical Bead blasting an engine block

Gonna build a couple Cadillac engines and I want to make them as clean as possible before the build. Parts aren't as readily available for them and everything costs more, so I just decided to be a little more detailed about cleanliness. I do like how engines look after shot blasting........kinda like a diamond in the rough.

Just talked to another local shop and they said $150 gets baked and shot blast.
