Product Details

The Cometic C5399-036 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Gen-1 Small Block V8 engines with aftermarket cylinder heads. This gasket features a 4.030-inch bore diameter and a .036-inch compressed thickness, making it ideal for performance applications requiring precise combustion sealing.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under high compression and boost conditions
  • 4.030-inch bore diameter accommodates various overbore and stroker configurations
  • .036-inch compressed thickness allows for precise compression ratio tuning
  • Undersized water ports designed for aftermarket heads, allowing custom port matching and coolant flow optimization
  • Engineered for Chevrolet Gen-1 Small Block V8 engines (262-400ci platforms)
  • Eliminates the need for additional sealants when properly installed

Cometic's MLS gaskets feature multiple layers of stainless steel with elastomeric coatings that micro-seal surface imperfections while maintaining excellent recovery properties. The undersized water port design gives engine builders the flexibility to customize coolant passages to match specific aftermarket cylinder head configurations, ensuring optimal sealing and performance in high-performance and racing applications.

Great Navigation and description

My son lives about 1500 miles from me. He had asked me to get him an Industries SuperFlow Hi-Volume Air Compressor for Christmas. <br>With a couple of click on my computer, the compressor was ordered to be shipped to him and was paid for. He had the exact compressor he requested within five days.(and that included the weekend)<br>One word sums up my experience---EASY

My order had a delay. I believe this was due to the fact that it was shipping from the manufacturer so I can't really blame Autoplicity. The customer service team did not originally respond to my first e-mail, but they did respond to me once I opened a dispute in PayPal and the issue was resolved. I couldn't find a better price on the part I ordered though (or anything remotely near that price for that matter).

Excellent prices and fast shipping! Exhaust showed up as described and good to go! Very happy
