Do I take it I would be ill advised to use the standard 7A valves and what would be the likely outcome if I did?? I have no idea whether the ones I have are sodium filled or not. Does anyone know how much new exhaust valves cost?'93 S4 Avant now back on the road complete with new shiny go faster bits. -
From what I understand Sodium filled valves aren't that much better than standard really. But I guess that manufacturers fitted them for a reason, perhaps reliabilty in extreme conditiosn? Pays ya money takes ya choice and all that...
As for getting a set you might have to buy a complete head as I doubt that anyone will want to split them out... unless Terrybullwon or someone doing a silly project has replaceed them with lighter and / or larger items.Cheers'en, AndyC

Just so happens i have a set or two....
Sodium filled valves are on all the 20vt heads the soduim melts at something like 109degs and acts as a salt shaker to disperse the heat more quickly
They are about £15+ vat for vag parts or PM if you want some 2nd hand ones

I have a brand new set of valves i bought from vagparts, there are not original Audi items but made by Febi. No idea if they are sodium filled but they were bought for an ABY engine. I paid £97 for the ten of them, open to offers.
