Isn't it shiny!
The final stage - painting! Now it's a case of making sure that all of those nooks and cranies get painted. The other side is making sure that you don't fill/get paint in to some of the holes (the cam follower and cylinder head oil drain holes in this case)
The final result is a painted (internally) block.
What next? A fair guess would be more: cleaning, wire brushing, painting!
