Description
A head gasket is your engine's critical seal—it prevents coolant and oil from mixing with combustion chambers while maintaining compression integrity. This MLS (Multi-Layer Steel) gasket is engineered for LS-series engines that demand reliable sealing under high boost, nitrous, or sustained high-RPM operation. Choosing the correct compression thickness ensures proper clamp load and prevents gasket failure, which can result in costly engine damage.
