Product Description

The Cometic C5505-060 is an MLX cylinder head gasket designed for GM LS Gen-3/4 small block V8 builds at a 4.040" bore. Its integrated stopper layer adds extra clamp load around the combustion seal, helping the gasket hold up under the higher cylinder pressures common in boosted or nitrous-assisted builds.

Built from the same proven materials as Cometic's standard MLS line, it installs dry with no sealants or re-torque needed. A strong choice for performance LS engine assembly or rebuilds running this bore size.
