In today's internet world you can find someone that has a problem with just about anything. But there is no factual basis for suggesting there is a problem with heli-coils in cast iron. It is a time tested (decades) and proven repair. Just as an example tens of thousands of cast iron spark plug holes have been repaired using them. Probably just as many exhaust manifold bolt holes. They are a staple of automotive machine shops around the world.
