Product Details

The Cometic C5816-045 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chevrolet Mark IV Big Block V8 engines. Engineered with a 4.320-inch bore diameter and .045-inch compressed thickness, this gasket provides superior sealing for high-performance and racing applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for maximum durability and reliability
  • 4.320-inch bore diameter accommodates performance builds and oversized bores
  • .045-inch compressed thickness allows precise compression ratio tuning
  • Advanced MLS design with multiple layers of stainless steel and elastomeric coatings
  • Superior resistance to combustion pressure and thermal cycling
  • Eliminates gasket failure common with standard composite gaskets in high-performance applications
  • Ideal for forced induction, nitrous oxide, and naturally aspirated performance engines

Cometic gaskets are manufactured using state-of-the-art materials and processes to ensure consistent quality and performance. The MLS design allows the gasket to conform to imperfect sealing surfaces while maintaining excellent combustion sealing, making it the preferred choice for engine builders and performance enthusiasts.

On Monday I placed an order for a Moroso Battery Switch (which was competitively priced BTW) and sitting here Wed afternoon I've got my switch in hand. Autoplicity was perfect every step of the way, including immediate notification of the order receipt, notification of shipment, even notification that it had been delivered (and it was waiting on my front porch). Packing was suitable too. Couldn't be happier. Buy with confidence. Kev

Quick turnaround and the best prices on the web!

I ordered a Derale 14204 Trans oil pan from Autoplicity -<br>it arrived quickly, in good shape (was well packed for shipment)<br>More than pleased.... (best price was a bonus)<br>-HBP-

Autoplicity had the lowest listing price for a part which I had done extensive research. To make the deal much sweeter, free shipping! On top of that, part was delivered in only a few days! Really, there was no reason NOT to order from them. Great prices and fast response are the reasons why I look forward to continued business with Autoplicity. Overall a positive experience, so I highly recommend.

Excellent prices, inventory and fast service. I placed my order on Saturday, Aug 4, it was shipped on Monday, Aug 6, and due to arrive on Friday. I will be a repeat customer with prices and service like this.

Very good price on k&n air filter, will definitely order from autoplicity again.

In a rush to get my car up and running, Autoplicity had the best price on the items I needed, and in stock as well as shipped quickly. Just what I was looking for, thanks!
