You can sandblast Cast iron all day with no problem.
Valve covers and oil pans are also not an issue because they've been used in an oily environment all their lives, and aren't in danger of rusting through (and blowing through by blowing sand at them).
The problem with sheet metal is directly proportionate to the extrusion pattern. If you have a broad flat panel like a hood, deck or roof, it's going to warp. Valve covers and oil pans have extrusion bends that prevent warpage from occurring.
Yeah, blast those puppies and have 'em powder coated to match.

Cast iron is usually not a problem. Be a little creful with the stamped steel parts or body parts. These can be warped if too much pressure is used. Make sure you get engine parts really clean afterwords. Just a couple of those little glass beads in the engine can do some real damage.

You're absolutely right. Welding on cast-iron parts which are //safety-critical// is totally unacceptable. It is impossible to make 100% reliable welds on CI. The welds are almost certain to have SOME cracks in them, no matter what procedures you use, no matter how good of a welder you are. For something that is subject to severe dynamic loads, constant vibration, and fatigue, there is a very good possibility a weld on CI will fail no matter how good it is. You son knows just enough about welding to be a danger to himself. My professional advice would be to drill at least two holes and inset high-strength bolts. If he is hell- bent on welding he needs to find an aftermarket yoke that's steel, not CI. The latter would be the most reliable option, though with bolts(plural) you have at least some warning of impending failure.

check into media blasting with baking soda there is no heat build up and only clean up you have of the parts blasted is soap and water and you dont have to contend with flash rusting like you do with sand or other course blasting agents

Sure--or use different media like walnut shells to keep heat distortion down.

yes you can, adjust air pressure, thinner the metal the lower the air pressure
