Product Details

The Cometic C5741-030 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for the Chevrolet 4.3L Gen-1 90-degree V6 engine. This precision gasket features a compressed thickness of .030 inches and a 4.155-inch bore diameter, providing an optimal seal between the cylinder head and engine block.

Key Specifications:

  • Multi-Layer Steel (MLS) construction for superior durability and sealing
  • Compressed gasket thickness: .030 inches
  • Bore diameter: 4.155 inches
  • Application-specific design for Gen-1 4.3L Chevrolet V6 engines
  • Engineered for 90-degree V6 configuration

Features and Benefits:

  • MLS technology provides multiple layers of stainless steel with elastomeric coatings for exceptional conformability
  • Resists blow-out and maintains seal integrity under high combustion pressures
  • Accommodates thermal expansion and contraction during engine operation
  • Designed to handle increased cylinder pressures in performance applications
  • Reusable design makes installation and removal more forgiving than traditional composite gaskets

Cometic Gaskets are manufactured in the USA using advanced materials and processes, making them a trusted choice for engine builders, racers, and performance enthusiasts. This gasket is ideal for stock rebuilds, mild performance builds, or as an upgrade from OEM gaskets on Gen-1 Chevrolet 4.3L V6 engines.
