The Cometic GM Gen-3/4 Small Block V8 Coolant Bypass Seals - C15034 is a precision-engineered head gasket.

The Cometic premium head gasket is engineered for high-performance and racing applications where OEM gaskets fall short. Built with Cometic's premium materials, this gasket meets or exceeds OEM specifications for durability and sealing performance. Precision CNC-machined to exacting tolerances, this gasket seals combustion, water jackets, and oil passages simultaneously — eliminating the need for multiple gaskets or sealing compounds.
