Cometic Gasket Automotive GM LT1/LT4 Gen-V Small Block V8 .051 in MLX

The Cometic head gasket for your LT1 or LT4 is engineered to handle serious power without compromise. Built with multi-layer steel construction and a .051-inch thickness, this gasket delivers the reliability you need whether you're running stock boost or pushing well beyond factory limits. The advanced sealing technology ensures zero leakage around the combustion chamber, keeping compression where it belongs and preventing coolant crossover issues that plague inferior gaskets.

When you're building a high-performance small block, every component matters—and your head gasket is no exception. Cometic's precision manufacturing means this gasket maintains a perfect seal across thermal cycles and pressure spikes, giving you the confidence to trust your engine through track sessions and spirited driving. The MLX material compound resists delamination and provides superior blowby control, whether you're boosting with a supercharger or naturally aspirated and turning up the timing.

If you're serious about LT power and want a gasket that matches the quality of your build, this is the part that belongs under your valve covers.
