Spartan MLS Head Gasket SBC 4.213 Bore x .051

The Spartan MLS Head Gasket SBC 4.213 Bore x .051 from SCE GASKETS is a precision multi-layer steel cylinder head gasket engineered for Small Block Chevy engines. This gasket is designed for engine builders and automotive enthusiasts who demand reliable sealing under high compression and elevated operating temperatures. Whether you're rebuilding a classic performance engine or assembling a street/race combination, a quality head gasket is critical to preventing coolant and combustion leakage.

Built with multi-layer steel (MLS) construction, the Spartan gasket delivers superior durability and conformability compared to traditional solid gaskets. The 4.213-inch bore diameter is precisely matched to small block Chevy cylinder heads, while the 0.051-inch compression thickness establishes the correct combustion chamber volume and compression ratio for your engine combination. MLS gaskets excel at maintaining a consistent seal across multiple pressure cycles and temperature transitions, making them the preferred choice for high-performance and modified engines. The layered steel construction also reduces the risk of gasket blow-out under sustained boost or nitrous applications.

Small Block Chevy engine builders—from 265 to 400-cubic-inch combinations—rely on the Spartan MLS Head Gasket for dependable, long-term sealing. This gasket is suitable for street engines, weekend warriors, and dedicated race applications. Proper installation requires a clean deck surface, correct head bolt torque specifications, and appropriate sealant application per manufacturer guidelines. The gasket ships as a single unit, ready for immediate use in your cylinder head assembly process.
