Topic: Exhaust Gaskets for Spring-Mounted headers?

[beveldrive]

I'm going to fit spring-mounted header pipes on my 750 endurance replica. But I've been looking at the copper ring gaskets supplied in my gasket set, and it seems to me there's no way they're going to crush and create a seal with just spring pressure.
Anyone had experience of spring-mount pipes?

If the spring tension is right, with the pressure and heat they are going to crush.

Use springs in my racer and the seals always come out flattened.

Use proper stainless exhaust springs with swiveling ends, normal steel ones will break

Sorry to bring this back from the dead, but why use springs at the head interface vs. the OEM split collar arrangement?  I have an aftermarket exhaust on my bike that uses some slip fit connections and springs to keep it together.  But at the head interface I just reused the OEM split collars and installed new copper crush gaskets. 

Is adding spring hooks and springs for that head joint simply a belts and suspenders approach?  Or is there something wrong with the split collar arrangement (besides weight)? 

+1 on the beehive springs with swivel ends.  They're great.

besides weight? better air flow/ cooling around this hot area ( I omit the collars altogether) , no cracked pipes due to vibration, speed to mount/unmount, enough?
