Product Details

The Cometic C5408-051 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Gen-1 Small Block V8 engines. This precision-crafted gasket features a .051" compressed thickness and is designed to accommodate a 4.200" bore diameter, making it ideal for performance builds and engines with larger-than-stock bore sizes.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme cylinder pressures
  • .051" compressed thickness allows for precise compression ratio tuning
  • 4.200" bore diameter accommodates over-bored and stroker engine configurations
  • Specifically designed for use with Brodix BD2000 cylinder heads
  • Engineered for Chevrolet Gen-1 Small Block V8 engines (262-400ci applications)
  • Stainless steel construction with multiple layers for maximum conformability and recovery
  • Viton rubber coating ensures exceptional sealing around combustion chambers and coolant passages

Cometic MLS gaskets are the preferred choice for high-performance and racing applications where traditional composite gaskets may fail. The multiple layer design allows the gasket to adapt to minor surface imperfections while maintaining consistent clamping pressure across the entire sealing surface. This gasket is particularly well-suited for supercharged, turbocharged, or nitrous-equipped engines where cylinder pressures exceed stock levels.

Quick Shipping and friendly Service

Autoplicity cares about there customers. I ordered a flash programmer and got to the last page and never got a confirmation of the order. I used the website chat and talked to somebody about it right away. So I ordered again and got a conformation. But both went though. Autoplicity called me next day a.m. to see if I made a mistake. Thanks for letting me know and correcting to one order. Saved me from shipping back a product I dind't need.

Good products with low prices. Easy website and pament options.

Exact product as promised with the best price on the internet. Product shipped fast and had a tracking number to keep me up to date on my order. I would order from again without hesitation and will tell friends.
