Welded j heads/w2

Looks like an awful lot of welding at the valve cover rail on those heads, too. And it does look like there is welding and the push rod holes around the intake ports have been welded on and hacked at. I'm starting to fear you may be exactly right about the "W2 Conspiracy Theory". I believe it would have been easier just to start a backyard foundry and cast them from scratch. The same degree of labor intensity either way you go, it absolutely is making my head swim thinking about the preheating cooling, machining, carbide usage, and God knows what else it would take.
