Any aftermarket steel valve permitted; must maintain stock head and stem size; titanium valves prohibited. (OEM sodium-filled valve may be replaced with titanium, provided weight is equal to or greater than original.)

Gosh, I read right past that! Thanks for the correction. I knew that used to be the wording to cover for the 427 Fords when the hollow stem sodium-filled valves were no longer available.
