What are you blasting it for? clean oil and grim or paint?
Yes, make sure to protect the injector bosses and the head mating surface.
Have a machine shop hot tank it for like $20
You can use glass bead,but tape off gasket surfaces,and injector holes,and coolant passages.
Once done,clean the dog poop out of it to make sure no glass winds up getting into the engine afterwards.
I would have a shop soda blast. Dissolves easily with washing. No sand or glass to get trapped.
