Product Details

The Cometic C5331-056 is a premium multi-layer steel (MLS) cylinder head gasket engineered specifically for Chevrolet Mark IV big block V8 engines. This gasket features a 4.630-inch bore diameter and .056-inch compressed thickness, making it ideal for high-performance and racing applications where superior sealing and durability are critical.

Key Features:

  • Multi-layer steel construction provides maximum sealing under extreme cylinder pressures
  • 4.630-inch bore diameter accommodates standard and oversized big block configurations
  • .056-inch (1.42mm) compressed thickness allows precise compression ratio tuning
  • Designed for Chevrolet Mark IV big block engines including 396, 427, 454, and 502 cubic inch variants
  • Superior heat resistance and reusability compared to composite gaskets
  • Eliminates gasket failure from excessive cylinder pressure in forced induction and high-compression applications

Cometic MLS head gaskets are the professional choice for engine builders who demand reliable sealing in demanding performance environments. The multi-layer steel design conforms to imperfections in the block and head surfaces while maintaining consistent clamping pressure across the entire sealing surface.

Great price and fast shipping. Can't wait to try these pads out!

Thanks for you swift respond for the email and your accurate information and i hope to deal with you again

Ordered a DiabloSport tuner for my truck here, as they had the lowest prices on the web with shipping. Order was placed on Saturday and shipped Monday. Although I received my tracking number on Tuesday, I was pleasantly surprised that they had already shipped it out. Nonetheless, my transaction was flawless. I would order from them again with no doubts.
