Default Sodium filled valves

Many years ago I had a 427MR that dropped an exhaust valve and broke a piston. Apparently the guy who did the heads used sodium filled valves and not the Manley valves I had specified. I never hear any talk about these valves and am assuming nobody uses them so they don't go through the nasty experience I had.

Anybody using these? They were supposed to be lighter I believe.
