Auto Zone or Kragens.

I can't remember the manufacturer, but it comes in a black tube and is called "ultra high-temp black" gasket maker or gasket sealer. It is RTV rubber material, but it is impregnated with stuff to make it run at higher temp than regular red or blue RTV.

ADD: It's made by permatex. here is a sitre showing what it looks like.
