Product Details

The Cometic C5246-040 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Gen-1 Small Block V8 engines. This precision gasket features a 4.100" bore diameter with a .040" compressed thickness, designed to provide superior sealing and durability in high-performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for maximum reliability and reusability
  • 4.100" bore diameter accommodates stock and slightly overbored engines
  • .040" compressed gasket thickness for precise compression ratio tuning
  • Compatible with 18-degree and 23-degree cylinder head designs
  • Round bore configuration ensures proper combustion chamber sealing
  • Exceeds OEM specifications for high-performance and racing applications

Cometic's MLS gaskets feature multiple layers of stainless steel with elastomeric coatings that conform to surface imperfections, providing exceptional sealing even under extreme cylinder pressures and temperatures. The round bore design works with Gen-1 Small Block Chevrolet engines including 262, 265, 283, 302, 305, 307, 327, 350, and 400 cubic inch variants when equipped with compatible cylinder heads.

This gasket is ideal for street performance, racing, and forced induction applications where stock gaskets would fail. The .040" thickness allows engine builders to fine-tune compression ratios when combined with deck height adjustments and piston selection.

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.

so far so good

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.

easy so far

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!!!!
