Cometic GM LS Gen-3/4 Small Block V8 .086in MLS Cylinder Head Gasket - 4.130in Bore

When you're rebuilding the top end of your GM LS Gen-3/4 small block V8, you need a cylinder head gasket that can handle the job. This Cometic MLS (Multi-Layer Steel) head gasket is built for that purpose, featuring a .086 inch thickness and a 4.130 inch bore to fit a wide range of LS engines found in vehicles like the Chevrolet Silverado, Cadillac CTS, and Chevrolet Corvette.

This gasket uses Cometic's HP shim technology, which is embossed around the combustion chamber. This design helps increase the clamping force right where it's needed most, improving the sealability, especially on open deck blocks. The outer layers are coated with Viton, a material known for its resistance to heat and oil, helping to ensure a long-lasting seal under demanding conditions.
