Ultimate Sealing for the Classic Datsun L28

Restore and enhance your classic Datsun 280Z or 280ZX with the Cometic 5-Layer MLS Head Gasket. Specifically designed for the L28 non-turbo engine with an 89mm bore, this .040-inch thick gasket provides the ultimate seal for high-output classic engines. Cometic's Multi-Layer Steel (MLS) technology is the gold standard for sealing aluminum heads to cast iron blocks, effectively managing the different expansion rates of these materials.

Why Choose Cometic MLS?

  • 5-Layer Construction: Increased strength and durability.
  • Viton Coating: Heat-resistant flour elastomer coating (up to 482°F).
  • No Sealants Required: Designed for a perfect, dry seal.
  • Corrosion Resistance: Engineered to withstand the test of time.

The outer layers are embossed and coated on both sides with Viton, ensuring a robust seal that resists shearing forces and prevents leaks. Whether you are performing a full engine restoration or a performance build, this gasket provides the reliability needed to push your L28 engine to its limits. By choosing this premium gasket, you ensure that your combustion chamber remains sealed under all driving conditions. Trust GGCRACING to provide the high-quality components your vintage Datsun deserves.
