Product Details
If you're rebuilding the top end of your Chevrolet Gen-1 Small Block V8, getting the head gasket right is crucial for a solid seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of higher output engines, offering a reliable seal without needing extra sealants. It's designed to work with both aluminum and cast iron blocks, and can withstand the stresses that come from mating different metals.
Cometic constructs these gaskets from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. The center layer is stainless steel, and its thickness can be adjusted to meet different requirements, with this particular gasket set to a compressed operating thickness of 0.027 inches and a 4.160-inch bore. These gaskets are also noted for having undersized water ports, which allows for customization when using aftermarket heads.
This gasket fits a wide range of Chevrolet and GMC trucks, SUVs, and cars from the early to mid-1980s, as well as some Avanti and Checker models. It's a well-built option for anyone looking for a dependable seal on their Gen-1 Small Block V8 build.
