Product Details

The Cometic C5816-070 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chevrolet Mark IV Big Block V8 engines. This high-performance gasket features a 4.320-inch bore diameter and a compressed thickness of .070 inches, making it ideal for both stock and modified big block applications.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme cylinder pressures
  • .070-inch compressed gasket thickness allows for precise compression ratio tuning
  • 4.320-inch bore size accommodates standard and slightly overbored big block cylinders
  • Embossed stainless steel layers with elastomeric coating ensure excellent conformability to deck surface imperfections
  • Designed to withstand high combustion temperatures and pressures in performance applications
  • Eliminates the need for additional sealants when surfaces are properly prepared

Cometic MLS gaskets are the choice of professional engine builders and racers worldwide. The advanced MLS design distributes clamping load evenly across the head-to-block mating surface, reducing the risk of gasket failure even in high-horsepower, turbocharged, or supercharged applications. Proper surface preparation with a minimum 50 RA finish is recommended for optimal sealing performance.

Easy to search, good pricing.

Fast, good price

You can tell customer service is important to this company. Not only were the prices lower than other places but they communicate the status of the order and shipping very well. They obviously care what people think. I was suspicious of all the positive comments but decide to try them anyways. Very happy I did and definitely plan on buying from them again.

This company offers profesional service at a very competitive price. The header collectors i ordered were not available at the big speed outlets. The fast shipping was also a plus. I would recomend Autoplicity to anyone who needs parts in a hurry !

Great price for the item, almost half off. Good website for auto parts

Easy to use web site. Quickly found what I needed. Smooth check out and SUPER FAST delivery. Couldn't ask for a better transaction experience. Bookmarked and for sure "GO TO" for next auto parts search. Thanks Autoplicity

I am impressed with they mail order service. Recommended.
