Is this correct?

Correct. You absolutely cannot run DLC against cast iron.
James Schaecter at one time was working with a company that coated both cast iron camshafts AND tool steel lifters. I have had 3-4 customers who have been very successful with that coating. I have only been using Trend lifters, my dealings with PPPC, or, actually, a customer's dealing with them, and my inquiry with them after the failure the customer experienced, turned me off of them permanently. I have been using Comp cams, and they have been nitriding my cams for me.
