The RAM AIR IV Pontiac Valves were actually a two piece valve joined together.
Years ago, Jim Brady, a PY Member, had the head of a RA-IV valve come off at Broadway Bob's drag strip in Wisconsin one night. Fortunately the engine had just finished a burn=out and was idling towards the starting line when the head came off.
No damage to the engine BUT no more racing that week-end.
ONE PIECE Ferrea Valves are a much better deal.
