The Cometic Gaskets C15453-042 is a high-performance exhaust header gasket specifically engineered for Holden 253, 304, and 308 cubic inch V8 engines. This gasket features Cometic's advanced ArmorCore construction with a .042-inch (1.07mm) thickness, providing exceptional sealing and durability in high-heat exhaust applications.

Key Features:

• ArmorCore construction with stainless steel armor around combustion openings for maximum blowout resistance
