Cometic MLS Cylinder Head Gaskets – Holden 304 / 308 / 5.0L / 355 Stroker

Cometic MLS cylinder head gaskets are a proven sealing solution for Holden 304, Holden 308, and Holden 5.0L V8 engines, making them an excellent choice for performance builds including the Holden 355 stroker. Designed for high-performance street, strip, and race use, these gaskets deliver reliable sealing under demanding conditions.

Cometic MLS gaskets are manufactured from multiple layers of stainless steel, providing excellent strength, rebound, and corrosion resistance. The embossed outer layers are coated with a Viton-based rubber material, allowing the gasket to seal effectively across a wide range of surface finishes and load conditions commonly found in modified Holden V8 engines.

These MLS head gaskets are ideal for aluminium cylinder heads on cast iron Holden blocks, as well as aluminium-to-aluminium combinations. The design resists the shearing forces caused by differing thermal expansion rates, a common issue in high-output Holden 304 and 308 engines.

Cometic MLS gaskets promote even clamping force across the deck surface, helping reduce bore distortion and improve long-term sealing. No re-torque is required, making them suitable for fresh builds and performance rebuilds alike.
