Product Details

The Cometic C5331-089 is a multi-layer steel (MLS) cylinder head gasket engineered specifically for Chevrolet Mark-IV Big Block V8 engines with a 4.630" bore diameter. This precision gasket features a compressed thickness of .089" (approximately 2.26mm) and utilizes Cometic's proven MLS construction for superior sealing performance under extreme conditions.

Key Features:

  • Multi-layer steel (MLS) construction with multiple embossed layers for maximum conformability and recovery
  • 4.630" bore diameter designed for Big Block Chevrolet Mark-IV applications
  • .089" compressed gasket thickness provides precise compression ratio tuning
  • Viton rubber beading around combustion chambers and fluid passages ensures reliable sealing
  • Stainless steel construction resists corrosion and withstands extreme temperatures and pressures
  • Ideal for high-performance, racing, and forced induction applications

Cometic MLS head gaskets are the choice of professional engine builders and racers worldwide. The multi-layer design allows the gasket to recover and maintain seal integrity through heat cycles and head lift, while the embossed layers provide multiple sealing points. This gasket is perfect for performance builds requiring precise bore sizing and thickness specifications to achieve target compression ratios.

Check out was very quick and easy. I also like how I was not forced to create an account to purchase

Very easy to order.

Cheapest priced ARP head studs on the internet. A++ I will definitely do more business with Autoplicity.

Processed and shipped fast. I was a little upset with them shipping my Eibach springs in the Eibach box, and not repackaging it. Everyone could see the box, and knew what was in it. But this will not stop me from ordering again.

Found what I needed at an unbeatable price, easy purchase! No issues

The correct product that I ordered, and easy to find through there web site.thanks
