I curious what would be the best sanding grit to finish with on porting aluminum and iron heads?

I finish Iron heads with a stone, grit would be like 80. Aluminum I finish with used 80 grits...more like 70 grit.

60 grit on intake to stop fuel droping out and 340 grit on exhaust port to help stop carbon build-up, this is from another forum and others here may know better, not my personal experience but is what I'll be trying. hope this helps.
