Copper is the standard by which all other conductors are measured, therefore a copper gasket provides superior thermal conductivity, acting to stabilize head and block temperatures which makes tuning easier. Copper (in the form we use) has a tensile strength of approximately 32,000psi, compare this to the 1200 to 1800psi tensile of most facing materials used on conventional performance head gaskets. 25% Elasticity coefficient . One of the properties of copper is that it stretches before final failure, hence providing an extra measure of safety in case of severe stretch.
