Need advice on new valves
I am rebuilding my 1980 911SC motor and need advice on valves. My machine shop says I need all new valves (Bent 6 exchust valves and intakes have been previously machined so there is not enough margin). He is suggesting using valves by a company called Intervalve. They are way less expensive than TRW valves, but I am not sure if they are sodium filled. This is a concern to me because this is a track car and I do not want to risk over-heating.
Please reply if you have done similar work or if you have any opinion on the various brands of valves available.
Thanks,
Don

Don: I've not used the valves that you mention, but I've had a hugely expensive problem in the past with valves made by a different manufacturer. I would never even consider anything other than o.e. for such a critical part.

Intervalves are genuine POS,...
Use the factory TRW ones.
