Salesperson/rep at Ferrea misunderstood. The valves are what get coated, not the seat inserts. Called Ferrea myself to get clarification. Thanks for chiming in guys. I'm glad I have somewhere to get some REAL info on stuff I'm not sure about. The turnaround time just becomes another delay on heads that I have not seen in a year, now. I'll live without the coating. At least I now know what to order for my next build. I question why I wasn't given this info/option when I was asked to upgrade to Titanium valves in the first place. Not a new process anymore.
