Product Details

The Cometic Gaskets C5247-051 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Generation 1 Small Block V8 engines. This high-performance gasket features a 4.125-inch bore diameter and .051-inch compressed thickness, making it ideal for performance builds and engine rebuilds requiring precise sealing and durability.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability under high combustion pressures
  • 4.125-inch bore diameter accommodates standard and slightly overbored small block Chevy applications
  • .051-inch compressed gasket thickness for accurate compression ratio calculations
  • Compatible with both 18-degree and 23-degree cylinder head angles
  • Round bore design with integrated steam holes for proper coolant circulation
  • Manufactured to OEM specifications with performance-grade materials

Cometic MLS gaskets utilize multiple layers of stainless steel with advanced coating technology to create a gasket that can withstand extreme cylinder pressures and temperature cycling. The integrated steam holes ensure proper coolant flow to critical areas of the combustion chamber, preventing hot spots and potential engine damage. This gasket is designed for use with Generation 1 Chevrolet Small Block V8 engines, including popular displacements like 265, 283, 302, 327, 350, and 400 cubic inch variants.

Autoplicity had the item I wanted at a cheaper price than anybody online or in stores. They didn't have the item in stock, but they were very informative as to the status of my item. They have shown unheard of customer service via email since the inception of my order. I will definitely do business with them again.

PIAA stuff ships slow but good prices

Good company to deal with, will gladly do business here again.

Navigating the site was easy

I would definitely recommend Autoplicity. I ordered Thule bike racks (THU-518), and the products arrived in 2 days in perfect condition. Plus the prices (along with free shipping) were the best on the web.
