LS HP MLS Head Gasket LS Small Bore

The LS HP MLS Head Gasket LS Small Bore is engineered for high-performance LS engine builds where reliability and combustion sealing are essential. This multi-layer steel (MLS) head gasket is designed for enthusiasts rebuilding or upgrading LS-platform engines, whether for naturally aspirated performance, turbocharged applications, or street-strip duty.

Constructed by STRAUB TECHNOLOGIES INC., this gasket serves as a critical interface between the cylinder head and engine block, effectively containing boost pressure, coolant passages, and combustion forces. The MLS technology utilizes multiple hardened steel layers with elastomer facing to evenly distribute clamping load across the combustion chamber, resisting blowby and maintaining compression even under high boost or cylinder pressure.

This gasket is particularly beneficial for owners of LS1, LS2, LS3, LS9, and smaller-displacement LS engines, ensuring precise port alignment and preventing compression loss at the head gasket sealing surface. Its design tolerates the thermal cycling and mechanical stress of forced-induction builds, modified ignition timing, and high-RPM operation, making it the choice for serious engine builders who prioritize durability.
