Product Details

The Cometic C5247-030 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chevrolet Gen-1 Small Block V8 engines. This precision-engineered gasket features a .030" compressed thickness and is optimized for engines with a 4.125" bore diameter.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 4.125" bore diameter with round bore design
  • .030" compressed gasket thickness
  • Compatible with 18-degree and 23-degree cylinder heads
  • Includes steam holes for proper coolant circulation
  • Precision-machined for accurate fitment on Gen-1 Small Block Chevy engines

Cometic MLS head gaskets utilize multiple layers of stainless steel with elastomeric coatings to provide exceptional sealing under extreme cylinder pressures. The round bore configuration with integrated steam holes ensures proper coolant flow while maintaining combustion seal integrity. Ideal for performance builds, forced induction applications, and high-compression engines where stock gaskets may not provide adequate clamping force.

Great delivery and product

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.

Excellent selection, great prices, and fast shipping. I am very satisfied.

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!

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