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

Did you post on the Pelican board too? There are a lot of engine rebuild discussions over there.
