Product Details

The Cometic C5248-045 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Gen-1 Small Block V8 engines. Featuring a 4.165-inch bore diameter and .045-inch compressed thickness, this gasket is designed to provide superior sealing and durability in high-performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for maximum strength and conformability
  • 4.165-inch bore diameter accommodates standard and slightly oversized small block Chevy builds
  • .045-inch compressed thickness allows precise compression ratio tuning
  • Compatible with 18-degree and 23-degree cylinder head angles
  • Round bore design with integrated steam holes for proper coolant circulation
  • Embossed stainless steel outer layers with special coatings resist corrosion and micro-welding
  • Designed to withstand extreme cylinder pressures in naturally aspirated and forced induction engines

Cometic MLS gaskets feature multiple layers of stainless steel with polymer coatings that micro-seal imperfections in the block and head surfaces. The spring-like characteristics of MLS gaskets allow them to recover and maintain seal integrity through repeated heat cycles, making them ideal for street performance, racing, and boosted applications. This gasket requires proper surface preparation with a minimum 50 RA surface finish for optimal performance.

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.

it was veryeay to order very good prices fast shipping

Thanks

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!
