can a cast exhaust manifold be welded and if not, does anyone have a passenger side r/h drive one for sale.thanks.
 
V8 are the same both sides, but the "S" is different to autos, and they can be welded but they crack again. Best way is to heat the manifold in an oven then braze it and allow it to cool slowly. I had a broken Jensen manifold repaired that way (by someone who knew what they were doing) and that lasted and is still OK AFAIK.
 
Years ago I worked at a fabricators, quite often cracked manifolds came in for repair. The shop was heated buy a large cylindrical wood burner made from an old pressure vessel. The manifolds would be placed in the woodburner for a while, stick welded with cast iron rods and then returned to the wood burner, and then cooled gradually, mostly it was a successful process.
