DNA Motoring GKTSET-SBC-SB Aluminum Exhaust Manifold Gasket Set for Chevy Small Block V8

Overview

The DNA Motoring GKTSET-SBC-SB is a complete gasket set designed for Chevy small block V8 engines, paired with aftermarket headers. It uses an aluminum reinforced graphite gasket to deliver a durable seal at the interface between the exhaust manifold and cylinder head. Heat cycles and age can wear gaskets, potentially leading to leaks and extra heat in the engine bay. Replacing the gasket helps restore the integrity of the exhaust connection and supports clean, consistent exhaust flow.
