Sam,

It is quite repairable if you stay away from
anything that has to do with arc weld or epoxy.
Epoxy will not stand up to the heat and arc
weld contracts so much that it will crack
before it is cool, also the thermal cycling
will continually add to that problem.
You need it on the bench ,a large torch to
heat it to a red glow, a smaller torch with
which to weld , some bare cast iron rod , and
a can of cast iron welding flux.

Manifold in the picture and the link was
repaired with torch and cast iron rod.
