Cometic GM Gen-V/VI Big Block V8 .044in MLS Cylinder Head Gasket - 4.630in Bore

This product is a Multi-Layer Steel (MLS) cylinder head gasket designed for GM Gen-V/VI Big Block V8 engines. It features a thickness of .044 inches and a bore size of 4.630 inches, making it suitable for a range of Chevrolet and GMC trucks and vans from the early 1990s, like the Chevrolet C1500 or GMC C2500 Suburban. This gasket is built to handle the demands of these powerful engines, ensuring a strong seal between the cylinder head and the engine block.

Cometic constructs this gasket using three to five layers of stainless steel. This material choice offers increased strength and resistance to corrosion, while also providing good rebound characteristics. The outer layers are embossed and coated on both sides with Viton, a heat-resistant rubber material that can withstand temperatures up to 482°F (250°C). This advanced coating helps the gasket meet tough sealing requirements across various conditions and surface finishes found on engine components.
