Cometic GM LS1/LS2/LS3/LS6 Gen-III/IV Small Block V8 4.080in Bore .040in MLS Cylinder Head Gasket

If you're rebuilding the top end of your GM LS Gen-III or Gen-IV small block V8, a solid set of head gaskets is crucial for a reliable seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these popular engines, whether you're working on a Camaro, Corvette, or Silverado. It's designed with a 4.080-inch bore and a .040-inch thickness, making it a direct fit for many LS-based applications.

Cometic uses HP shim technology in these gaskets, which helps increase the clamping force around the combustion chamber. This is especially important for open deck blocks, as it creates a stronger seal and helps prevent leaks. The outer layers of the gasket are embossed and coated with Viton, a material known for its resistance to heat and oil, further ensuring a long-lasting seal under pressure.

This gasket is a well-built option for anyone looking to get their LS engine back together with confidence. It's a popular choice for both street and performance builds where a dependable seal is a top priority.
