Cylinder Head Gasket MLS 3.950 Bore GM LS

The Cylinder Head Gasket MLS 3.950 Bore GM LS is an essential sealing component for LS engine builders and performance mechanics focused on maintaining combustion chamber integrity. This gasket is ideal for various applications, including stock 5.3L assemblies, 6.0L tuning, and high-output stroker builds.

Constructed from multi-layer steel (MLS), this gasket provides superior conformability to imperfect deck surfaces and exceptional resistance to thermal cycling. The elastomer-coated steel laminations allow for slight flexing under load, accommodating minute variations in head and block finishes that occur during machining and assembly.

Engine enthusiasts will appreciate the reliability of this gasket in both street and race applications, where maintaining a critical seal between the cylinder head and block is paramount. Designed specifically for the Gen III and Gen IV LS platform's 3.950-inch bore specification, it ensures proper fire-ring positioning and combustion chamber protection.
