phenolic intake gaskets -- experiences?

Wondering if anybody has tried phenolic intake gaskets and has any results?

Supposedly, this type of gasket reduces heat conduction through the block into the intake manifold (and from intake manifold into charge air). This seems good in theory, but am curious just how much this really helps compared to good heat-shielding and a properly ventilated engine bay.
