Cometic Chrysler 6.1L Gen-3 Hemi .030in MLS Cylinder Head Gasket - 4.100in Bore

If you're rebuilding the top end of your 6.1L Gen-3 Hemi engine, a solid head gasket is crucial for sealing combustion pressure. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines, ensuring a reliable seal between your cylinder heads and block.

Cometic uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes. This gasket is designed for a 4.100 inch bore and is 0.030 inches undersize, which is important to note if you're machining your block or heads. MLS gaskets are ideal for combinations of aluminum heads with either aluminum or cast iron blocks, as they can manage the different expansion rates between the metals.

Because these are MLS gaskets, they don't require any additional sealants, simplifying installation. They are well-built to provide maximum sealing performance for your engine build.
