Cometic Gasket - LT1/LT4/LT5 Gen-5 Small Block V8 .021 in MLS Exhaust Manifold Gasket Set

Seal your LT1, LT4, or LT5 exhaust manifolds with the kind of reliability that keeps high-horsepower builds running strong. Cometic's multi-layer MLS construction uses stainless steel throughout for superior strength and corrosion resistance, ensuring these gaskets won't fail when you're pushing your engine hard. The embossed outer layers are coated in heat-resistant Viton that handles temperatures up to 482°F, creating a barrier that seals consistently across varying surface finishes and load conditions without degrading.

Built for the demands of forced induction, nitrous, and high-output naturally aspirated engines, this .021-inch gasket set is engineered to maintain a secure seal cycle after cycle. If you're serious about extracting maximum power from your Gen-5 small block and keeping exhaust gases exactly where they belong, Cometic's proven engineering belongs under your hood.
