Just a thought, but an engine builder buddy of mine opines that since the blocks and manifolds were sand cast originally, they must have had a way to get the sand out reliably. That's why there are all those extra holes.

The manifold needs to be cleaned since the inside has some surface rust and some rust particles that are falling out. Can I bead blast the unit and how do I clean it up so no particles fall into the engine after it is installed? I plan on buying a bench top blaster, so this might be the perfect excuse to get one. Or, would I be better off sending the part out to get cleaned and dipped? The underside has an aluminum cover that looks like it is riveted on. Can this be removed and can I get replacement rivets to put it back on. After it is clean, should I use any paint on the underside to stop any ne rust particles from forming?
