Product Details

The Cometic C5816-080 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Mark IV Big Block V8 engines with a 4.320-inch bore diameter. This gasket features a compressed thickness of .080 inches, providing excellent sealing performance for high-performance and racing applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • .080" (2.0mm) compressed thickness for precise compression ratio tuning
  • 4.320" bore diameter designed for standard and slightly over-bored big block Chevy engines
  • Embossed stainless steel layers with synthetic rubber coating resist high cylinder pressures
  • Accommodates minor deck surface imperfections while maintaining combustion seal
  • Ideal for street performance, drag racing, and marine applications

Cometic MLS gaskets are designed to handle extreme temperatures and pressures, making them an excellent choice for boosted, nitrous, or naturally aspirated high-compression engines. The multi-layer design allows for engine movement and thermal expansion while maintaining a reliable seal between the block and cylinder heads.

Great price, great service, A+

Fast shipping, great product. Nothing more needs to be said.

great price and customer service

They had the parts I needed at the best price. I needed some questions answered to make sure I was ordering the right parts for a 4 year old car and they were very helpful when I called.

Best price on the internet for my parts. Shipped out the next morning.

Finding my parts on this website was incredibly easy. The prices were the lowest around and I was kept up to date about the estimated delivery date. Order #19058

Adequate.

Ordered a Trac-Bar from Autoplicity, and didn't have any problems. WILL be back!

Easy ordering and when i did have a question they answered right away! best price on the product too!
