Cometic Chrysler 6.1L Hemi 4.125in Bore .051in MLS Head Gasket

When you're rebuilding the top end of your 6.1L Hemi engine, a solid head gasket is crucial for sealing combustion pressure. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of high-output engines, ensuring a reliable seal between your cylinder head and engine block. It's designed to work with both aluminum heads on aluminum blocks and aluminum heads on cast iron blocks, resisting the shearing forces that can occur between different metals.

Cometic constructs these gaskets with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482°F (250°C). This coating helps create a robust seal even in harsh conditions and on various surface finishes. The compressed operating thickness of this gasket is .051 inches, and it requires no additional sealants, making installation more straightforward.
