Cometic Chevy Gen1 Small Block V8 .080in MLS Cylinder Head Gasket - 4.125in Bore - 18/23 Degree Head

When you're rebuilding the top end of your Chevy Gen-1 Small Block V8, you'll get a set of Cometic Multi-Layer Steel (MLS) head gaskets. These gaskets are built with multiple layers of stainless steel, giving them strength and the ability to rebound while resisting corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and works well with both aluminum and cast iron blocks. This particular gasket has a compressed thickness of .080 inches and a bore size of 4.125 inches, designed for 18/23 degree cylinder heads and includes steam holes.

Cometic MLS gaskets are a solid choice because they don't require any additional sealants, making installation more straightforward. The multi-layer design provides excellent sealing performance for engines that are putting out more power than stock. They are well-suited for applications where aluminum heads meet aluminum blocks, or aluminum heads meet cast iron blocks, as they can handle the different expansion rates between these materials.
