This gasket features a 4.160-inch bore diameter with a compressed thickness of .030 inches, making it ideal for high-compression builds and performance applications.

Key Features:

  • Multi-Layer Steel construction provides superior sealing and durability under extreme cylinder pressures
  • 4.160" bore diameter accommodates standard and mild overbore applications
  • .030" compressed thickness allows for precise compression ratio tuning
  • Undersized water ports designed for aftermarket cylinder heads, allowing customization of coolant flow
  • Engineered for use with aftermarket performance heads on Gen-1 Small Block Chevy engines (265, 283, 302, 305, 327, 350, 400)
  • MLS design features multiple layers of stainless steel with elastomeric coatings for maximum conformability

Cometic MLS gaskets are the choice of professional engine builders and racers worldwide, offering exceptional reliability in high-performance and racing applications. The undersized water ports provide flexibility when matching to various aftermarket cylinder heads, eliminating the need for extensive machining while ensuring proper coolant flow management.

Great price and fast shipping.

Fast shipping, great price, product was somewhat hard to install but got it done, love the outcome of it. Overall happy.

Cheaper than summitracing for arp headbolts. Fast processing and shipping.

I would definitely order my auto parts from your shop again. I was impressed with the prices and the correspondence. Thanks!

Order Number: 17562<br>I have delt with Autoplicity several times. They have great prices, always ship fast and have great communation. I always check to see if they have what I am looking for before I look some where else.

Unbeatable price and super fast shipping! The website is easy to navigate and there is a wide range of products to choose from. No need to go to the auto parts store when you have Autoplicity.com

I purchased a wind reducer for my cross bars, autoplicity had the best price availalbe, my order shipped timely and I received communications throughout the process. I will use this site again.
