I'm not gonna be much help. I never MIGed aluminum and I never worked with cast aluminum either.
I know that when people weld cracks in cast iron (not a simple process), they drill the two ends of the crack so it cant go any further out. not sure if that's needed with aluminum, but it might be good to do just as a precaution.
