I would definately swap out the titanium exh. valves for new ones!!.....they tend to get brittle, and break the heads off.
Dont want that happening to a cool old FE 427!!

The heads had hollow stem Sodium cooled exhaust valves from the factory! changed them out 20 years ago!!

Yes, those were prone to breakage too!!
