who runs dampeners? On a double valve spring, often there is a dampener in between the inner and outer (some double and most tripple spring setups don't have them). Most people run it, but I have heard of people not using it (though don't know the reason behind not). What would be the pros and cons of running and not running the dampener (just run the inner and outer straight)?

I had em in my 987 Comp doubles, and they were supposed to quiet things down a bit, but I still had a singer sewing machine. My new Crane 832 dual springs don't have em and I don't notice any difference.
Dampers tend to wear grooves in the retainers and spring cups/spring seats or shims. Leave them out if you can. You will lost some load by removing them. Just check to see if you have the proper load after removing.

Ron Proctor is the father of the modern performance spring, he consulted many cam companies over the years, designing springs for the best. He retired in the early 90's. I got the chance to meet him and in speaking with him, he felt dampeners were a must in valve springs to hold down harmonics.

The only thing that could be quieted down and/or eliminated noise-wise on an engine with racing fuel is detonation, i.e. pinging
