Cometic GM LS Gen-3/4 Small Block V8 .030in MLS Cylinder Head Gasket-Bore 3.910in

What you get here is a Cometic Multi-Layer Steel (MLS) cylinder head gasket, specifically sized at .030 inch thick with a 3.910 inch bore. This gasket is built for GM LS Gen-3 and Gen-4 small block V8 engines, and it comes with Darton MID Sleeves already integrated. These gaskets are a popular choice when rebuilding or upgrading engines like those found in a Chevrolet Camaro, Corvette, or Pontiac GTO, offering a solid seal for demanding applications.

Cometic builds these MLS gaskets using multiple layers of stainless steel, which gives them strength and the ability to rebound, helping to resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle high temperatures up to 482°F (250°C) and works well with different head and block materials, including aluminum to aluminum or aluminum to cast iron. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, like the .030 inch compressed thickness you get with this specific gasket. Because of their construction, these gaskets don't require any additional sealants, making installation more straightforward.
