Product Details

The Cometic C5551-052 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chevrolet Generation 1 Small Block V8 engines. This gasket features Cometic's advanced MLX construction, which combines multiple layers of stainless steel with a proprietary coating system to provide superior sealing and durability under extreme conditions.

Key Specifications:

  • Bore Size: 4.220 inches (suitable for stroker and overbore applications)
  • Compressed Thickness: .052 inches (1.32mm)
  • Multi-Layer Steel (MLS/MLX) construction for maximum strength and reliability
  • Round bore design for optimized combustion chamber sealing
  • Compatible with all aftermarket performance cylinder heads
  • Engineered for high-performance and racing applications

Features and Benefits:

  • MLX coating provides enhanced sealing around combustion chambers and coolant passages
  • Multiple steel layers absorb and distribute cylinder pressure evenly
  • Maintains seal integrity through extreme temperature cycling and pressure fluctuations
  • Eliminates the need for re-torquing after initial installation
  • Resistant to corrosion and coolant degradation
  • Ideal for turbocharged, supercharged, and naturally aspirated engines

This gasket is designed for engine builders and performance enthusiasts who demand race-proven reliability. The .052" compressed thickness allows for precise compression ratio tuning and proper piston-to-head clearance in modified engines. Compatible with Gen-1 Chevrolet Small Block engines including 262, 265, 267, 283, 302, 305, 327, 350, and 400 cubic inch variants when bored to 4.220" or larger.

I found parts for my car from google shopping and wanted to verify that everything was correct before order. I call the phone number and somebody picked right up and checked on everything for me. A++ seller. Thanks Autoplicity!

Excellent business. This is my second purchase and there will be more! I ordered my parts over the holiday weekend and they mailed them the Tuesday after Labor Day. The absolute BEST pricing you will get. You will not find a lower price else ware. The shipping doesn't even take forever like most places you get great pricing. Communication is excellent, the site is very easy to use and navigate. I will be doing business with Autoplicity.com many more times and highly recommend them.
