[pontiacjeff]

anyone heard about these yet? i just read in the "Family Tree" about the 2005 3500 using them. what if any advantage do they offer? turbo use??

From what I've read on graphite head gaskets, they're good to use in bi-metal engines(iron block + aluminum heads) because they can withstand the expansion a bit better. I also read that they seal really well and dissipate heat better then a conventional head gasket. They're supposedly ideal for boosted applications.

From the 2004 3400 release notes....

The 3400 V-6 is now equipped with graphite head gaskets. The gaskets feature a layer of graphite applied over the perforated stainless steel core to enhance gasket durability and optimize performance over the life of the engine. The graphite improves performance at all temperatures and provides excellent sealing, compression recovery and coolant resistance. Moreover, the gaskets have a thicker flange than before to improve durability.
