Spartan MLS Head Gasket SBC 4.067 Bore x .051

The Spartan MLS Head Gasket SBC 4.067 Bore x .051 from SCE Gaskets is specifically designed for small-block Chevy engines that require precision sealing under high combustion pressures. This gasket is ideal for those rebuilding a stock 350, tuning a street performance motor, or assembling a dedicated race engine.

Featuring a .051-inch thickness, this multi-layer steel gasket ensures optimal head clamping load distribution. Its MLS construction provides a flexible yet durable seal that adapts to surface variations while maintaining integrity under thermal cycling and boost. Unlike traditional composite gaskets, this design minimizes the risk of failure due to repeated heat stress.

This gasket is particularly beneficial for 350-based strokers, 383s, and similar combinations, where precise deck heights and surface finishes are crucial. Installation requires proper head bolt torque specifications to ensure a reliable seal, making it an essential component for any serious engine build.
