Product Details

The Cometic C5754-045 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Buick Big Block V8 engines. This high-performance gasket features a 4.385-inch bore diameter and .045-inch compressed thickness, providing exceptional sealing capability for stock and modified applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior durability and conformability
  • 4.385-inch bore diameter engineered for Buick Big Block V8 engines
  • .045-inch compressed thickness for precise compression control
  • Advanced coating technology ensures optimal sealing under extreme temperatures and pressures
  • Eliminates gasket failure and coolant leaks common with traditional composite gaskets
  • Ideal for performance, racing, and high-boost applications

Cometic MLS gaskets utilize multiple layers of stainless steel with specialized coatings that allow the gasket to adapt to flange imperfections and maintain seal integrity through thermal expansion and contraction. This design makes them the preferred choice for engines producing high cylinder pressures and demanding racing conditions.

Autoplicity had the part I needed. They had the best price I found. Shipping was a little slow. Overall I am very satisfied with the transaction and will be buying from them in the future.

Looked around online everywhere for my spark plug set. Autoplicity had what I wanted at the lowest price. Thanks guys!
