Cometic GM LS9/LSA Gen-4 Small Block V8 .044in MLX Cylinder Head Gasket - 4.100in Bore - RHS

If you're rebuilding the top end of your GM LS9 or LSA Gen-4 V8 engine, getting the right head gasket is crucial for a solid seal. This Cometic MLX head gasket is built to handle the demands of these high-output engines, ensuring your cylinder heads stay properly sealed against the block.

Cometic uses a Multi-Layer Steel (MLS) construction for these gaskets, which means they're made from multiple layers of stainless steel. This design offers increased strength and the ability to rebound, helping to resist corrosion and withstand the forces between aluminum heads and cast iron blocks. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C), making it ideal for harsh sealing environments. The center layer is stainless steel and can be varied to achieve different thicknesses; this particular gasket has a .044 inch thickness and a 4.100 inch bore, designed to fit specific LS9/LSA configurations.

These MLS gaskets don't require any additional sealants, simplifying installation. They are a well-built option for both aluminum-to-aluminum and aluminum-to-cast iron block setups.
