Product Details

The Cometic C5331-058 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Mark IV Big Block V8 engines. This precision-manufactured gasket features a 4.630-inch bore diameter and a compressed thickness of .058 inches, making it ideal for performance and racing applications.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme cylinder pressures
  • 4.630-inch bore diameter accommodates stock and slightly over-bored Big Block applications
  • .058-inch compressed thickness allows for precise compression ratio tuning
  • Stainless steel construction resists corrosion and maintains integrity at high temperatures
  • Engineered specifically for Chevrolet Mark IV Big Block V8 engines (396, 402, 427, 454 platforms)
  • Eliminates the need for re-torquing after initial installation
  • Excellent for street performance, racing, and forced induction applications

Cometic MLS gaskets utilize multiple layers of stainless steel with a proprietary coating system that ensures optimal sealing across the entire combustion chamber. The embossed layers provide micro-sealing at the head and block surfaces while remaining flexible enough to compensate for minor surface imperfections and thermal expansion.

Good website, Thought the fuel jugs would come with a pour spout. They are only the jugs though.

My Superchips Cortex arrived within a few days of order and by far was the best price arround. Product arrived in perfect condition and worked as described. Great deal. Order #10984

Thanks again! Best prices I found on the web! Fast shipping Would definitely buy from again!

In a rush to get my car up and running, Autoplicity had the best price on the items I needed, and in stock as well as shipped quickly. Just what I was looking for, thanks!

Great price. Minor problems with shipping because of UPS (dropped box and broke part, late delivery). Autoplicity sending me out replacement part.
