Titanium Valves Allowed in S/S?

If any one has the chance to buy New old stock the exhaust sodium filled pass on them as the sodium reacts to the steel and eats away from the inside out.

I recently held a 427 / 425 HP Ford intake valve from an old Hollman-Moody engine built in 1967 or so (the fishing boat engine I brought up on this forum). When disassembling the heads the head on an intake vale broke off. The dang thing was rifle drilled in the stem! Couldn't believe how light it was and it was a pretty large diameter valve. Now I know the exhaust are sodium filled on this engine but I didn't know they were doing this to intake valves back in the '60's.

I'd have to say I'm with SS Engine guy and others on this. Based on my limited experience, I can't see the need. Sure it may be faster but I see no other benefit. Cost goes up, maintenance and replacement goes up and engine damage can be a real issue if one breaks.
I lost two Stocker engines thanks to Mr. Schubeck, don't think I would want to go down this road.[/QUOTE]
