Product Details

The Cometic C5246-045 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Gen-1 Small Block V8 engines. This high-performance gasket features a .045" compressed thickness and is designed to accommodate a 4.100" bore diameter, making it ideal for both stock rebuilds and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme conditions
  • .045" compressed thickness allows for precise compression ratio tuning
  • 4.100" bore diameter with round bore design
  • Compatible with 18-degree and 23-degree cylinder heads
  • Engineered specifically for Chevrolet Gen-1 Small Block V8 engines (262-400 cubic inch)
  • MLS technology conforms to surface imperfections for optimal sealing
  • Embossed stainless steel layers with FKM (Viton) rubber coating resist high temperatures and combustion pressures

Cometic MLS gaskets are a popular choice among engine builders and performance enthusiasts due to their ability to withstand the demands of high-compression, turbocharged, and supercharged applications. The multiple layers of stainless steel provide excellent recovery characteristics and maintain seal integrity through repeated heat cycles.

Had the product I needed at a price that couldn't be beat. The shipping was a little high, but not completely out of line, either, and it was still better than other companies who have even MORE ridiculous shipping rates. Will buy from them in the future if they have what I need.

Found the items right away and it was a great price.

Great price and fast shipping!

Great prices and easy transaction

Best price I could find on line, shipped really fast. With how low the price is I was worried but everything came fast and it was the correct parts. This place really keeps the cost of racing down.

Everything went seamlessly. I placed my order on a Thursday and it got here Tuesday morning. No problems, and it was the best price I could find.

Had exactly what I wanted. Shopping cart did not have an update button for new quantity

Had to upgrade to a Snell 2010 helmet this year, bought the identical helmet for $200 less than I paid 8 years ago! Fast shipping, I will be checking Autoplicity first in the future!

GOOD PRICE! way to go keep up the good work!!!!
