Product Details

The Cometic C5816-120 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Mark IV Big Block V8 engines. This premium gasket features a 4.320-inch bore diameter and .120-inch compressed thickness, providing exceptional sealing performance for high-performance and racing applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior durability and heat resistance
  • 4.320-inch bore diameter designed for Mark IV Big Block engines
  • .120-inch (120 thousandths) compressed gasket thickness
  • Provides excellent combustion sealing in high-compression and forced induction applications
  • Accommodates thermal expansion and engine movement better than traditional composite gaskets
  • Reusable design allows for multiple installations when properly maintained

Cometic MLS gaskets are a trusted choice among engine builders and racers who demand maximum reliability under extreme conditions. The multi-layer steel construction creates a stronger seal around the combustion chamber while maintaining flexibility to accommodate cylinder head and block irregularities. This gasket is ideal for performance street engines, drag racing, road racing, and marine applications where durability and consistent sealing are critical.

Ordered a THULE 9001 bike rack. Shipping was prompt as well as the best price on the web. Will be back for business!<br><br>

I just bought two of the new Aeromotive pumps from autoplicity at the best price found online.. They were shipped out quick and arrived even faster than I thought. Autoplicity.com will be in my favorites when it comes to ordering parts for my 94 Supra from now on!!!

My first experience with Autoplicity has been great. One of the best prices I found for the item. Too, the company is not secretative about itself such as another parts discounter.<br><br>Autoplicity is now "bookmarked" for future purchases!

Really handy being able to pay through Amazon.

Great price! Quick shipping. The intake I ordered was $20.00 cheaper than anywhere else I looked. Item was instock and shipped quick. Will order from Autoplicity again!

Great Seller. Fast Shipping and great prices!

Great price and great service highly recommended. Will purchase again

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.

Great prices, quick processing, and an overall excellent company
