Product Details

The Cometic C5245-089 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Generation 1 Small Block V8 engines. This precision gasket features a 4.060" bore diameter and .089" (2.26mm) compressed thickness, making it ideal for performance builds and engines with increased compression ratios.

Key Specifications:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 4.060" bore diameter accommodates standard and slightly overbored small block applications
  • .089" compressed gasket thickness
  • Designed for 18-degree and 23-degree cylinder head angles
  • Round bore design
  • Compatible with Chevrolet Gen-1 Small Block V8 engines (262-400 cubic inch)

Performance Benefits:

  • MLS construction provides exceptional combustion sealing under extreme cylinder pressures
  • Multiple layers of stainless steel with elastomeric coating conform to imperfect sealing surfaces
  • Withstands high heat and pressure in performance and racing applications
  • Maintains seal integrity through repeated heat cycles
  • Eliminates the need for retorquing after initial installation

Cometic MLS gaskets are the preferred choice for professional engine builders and serious enthusiasts. The advanced materials and manufacturing processes ensure reliable sealing in street performance, drag racing, road racing, and marine applications. This gasket is designed to work with both aftermarket performance heads and original equipment cylinder heads on Gen-1 Chevy Small Block engines.

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.

I ordered new leaf springs for my Jeep Cherokee. Its already headed out to me. Ordering was nice and easy. I'll post more once i get it.

Excellent, easy, fast.

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 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!
