Professional-Grade MLS Head Gaskets for SBC

When building a high-performance Small Block Chevy, the head gasket is the most critical seal in the engine. The SCE Gaskets Spartan Multi-Layer Steel (MLS) head gasket is engineered to handle the stresses of high-compression and forced-induction environments. Featuring a 4.103-inch bore and a .039-inch compressed thickness, this gasket is designed to provide the perfect quench area for your combustion chamber, helping to maximize power output and combustion efficiency.

Key Features

  • Construction: Multi-Layer Steel (MLS) for maximum durability
  • Bore Diameter: 4.103 in
  • Compressed Thickness: 0.039 in
  • Application: Small Block Chevy (SBC)
  • Reliability: Excellent thermal expansion resistance

The Spartan series utilizes advanced steel layers that provide a superior seal around the cylinder bores, ensuring that your engine maintains maximum cylinder pressure. Unlike traditional composite gaskets, the MLS design is virtually immune to the common failures caused by heat cycles and high-boost applications. The .039-inch thickness is an ideal choice for builders looking to optimize their compression ratio while maintaining proper piston-to-head clearance. Whether you are prepping for a street-strip build or a dedicated race engine, these gaskets offer the peace of mind that comes with professional-grade engineering.
