Product Details

The Cometic C5755-051 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Buick Big Block V8 engines. This high-performance gasket features a 4.400-inch bore diameter and 0.051-inch compressed thickness, providing an optimal seal between the cylinder head and engine block.

Key Features:

  • Multi-Layer Steel construction for superior sealing and durability
  • 0.051-inch compressed thickness for precise compression ratio tuning
  • 4.400-inch bore diameter designed for Buick Big Block V8 applications
  • Advanced coating technology prevents corrosion and enhances sealing
  • Engineered to withstand high cylinder pressures and temperatures
  • Eliminates the need for re-torquing after initial installation

Cometic MLS gaskets are constructed from multiple layers of stainless steel, with an advanced coating system that ensures consistent clamping pressure across the entire sealing surface. This design accommodates engine movement and thermal expansion while maintaining a reliable seal, making it ideal for both street performance and racing applications. The gasket's construction provides excellent resistance to combustion gases and coolant migration, ensuring long-term reliability in demanding conditions.

Item shipped 5 days after order was placed. Worth the wait for the great price however. Order Number: 18722

Very nice looking item. Now I just got to get it installed. Prompt shipping and best prices anywhere.

Ordered a product and received within 2 days. Easy transaction and quick delivery.

quick

I think I had to remind them to ship my item but once I did it shipped the next day. The package had the wrong label on it so I wondered if I got the right item but I did and all is well.

No issues at all and a very good price to boot. What could be better? Will definitely order from them again.
