Product Details

The Cometic C5816-066 is a 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 precision gasket features a .066-inch compressed thickness, providing excellent sealing performance for high-performance and racing applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior durability and recovery
  • 4.320-inch bore diameter designed for Chevy Mark IV Big Block V8 engines
  • .066-inch (1.68mm) compressed thickness
  • Viton rubber coating on embossed stainless steel layers for maximum sealing
  • Handles extreme cylinder pressures and temperature fluctuations
  • Ideal for high-compression, turbocharged, supercharged, and naturally aspirated applications

Cometic MLS gaskets are constructed from multiple layers of stainless steel with a Viton rubber coating, allowing them to recover and maintain seal integrity under severe conditions.

This gasket is designed for use with performance engines where precise compression control and reliable sealing are critical.

<br><br>Borgeson 000940<br><br>I found Autoplicity during a price search on the Borgeson steering shaft for my truck. I had never heard of them, and was a bit skepticle. But after doing some research, found that Autoplicity has a good reputation on a Jeep forum I visit.<br><br>I decided to order, and I am impresed. Extremely fast shipping, I placed my order on Saturday, and its now Monday before noon. I am holding the new part!

Best price around. Great Communication. Fast shipping. What else can I ask for?<br>I have already purchased again from them.

Quick shipping and they had the fuel jugs I needed for the best prices thanks!<br><br>UPDATE: they were so good I made another order with them within a week.

Great service. Shipping cost is higher than most but fast.

Great Pricing (lowest i can find anywhere) and Quick Shipping, Product has no damage from shipping! Thank you Autoplicity!

I received my ARP head studs as described and on time with zero problems, and cheaper than anywhere else.Will use again!!!

We ordered a cover for a pickup truck bed and were so pleased that it was shipped so quickly. The price was the lowest that we found on the internet or in any of the stores where we looked. We were notified by e-mail as soon as it shipped. We will definitely shop this site again.

First time buyer from Autoplicity and found the website easy to navigate and find what I wanted quickly. They had the best price of all the other sites I checked, including shipping.
