LA 318 to Magnum 360 swap

I have a question about the intermediate shaft.
The shaft in the Magnum engine is steel correct?
If I go with a cast iron LA roller cam then I need to get a cast iron intermediate shaft?

Ask for a cast iron cam core,that will work with a LA intermediate shaft. I recommend Mopar P3690715 (heavy duty piece,IMO).
