Aluminum plate on cast iron manifold would seem to need a gasket, no? Thinking they have quite different rates of thermal expansion.

Well...... just imagine them hitting the turbine impeller!

Yes, as previously stated I did reuse the gaskets. They were worn but intact. Some kind of meshlike material? I'll see if I can get a photo of it.

Didn't see any crack in your photos.

Nope, cast iron manifolds, especially old well-used ones, are notoriously hard to weld successfully. But maybe you know an old-timer with a proven track record?
