Product Details

The Cometic C5399-027 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Generation 1 Small Block V8 engines. This high-performance gasket features a 4.030-inch bore diameter and a compressed thickness of .027 inches, making it ideal for performance builds and engine rebuilds.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under high-performance conditions
  • 4.030-inch bore diameter accommodates standard and slightly overbored small block Chevy applications
  • .027-inch compressed thickness allows for precise compression ratio tuning
  • Undersized water ports designed for aftermarket cylinder heads, allowing custom machining and port matching
  • Compatible with Chevrolet Gen-1 Small Block V8 engines including 265, 283, 302, 305, 327, 350, and 400 cubic inch variants

Cometic MLS gaskets utilize multiple layers of stainless steel with advanced coating technology to maintain a superior seal in extreme conditions. The undersized water port design gives engine builders the flexibility to machine coolant passages to match specific aftermarket head configurations, ensuring optimal coolant flow and eliminating potential leak paths.

Excellent customer service....<br>fast delivery<br>and good quality parts<br><br>

My second time ordering from Autoplicity. I price shop online and Autoplicity had the lowest price both times. Fast ship with email notifications. Autoplicity will now be my "First" site I go to for my auto accessories. Great job Autoplicity.

Great prices, quick shipping, customer service a bit difficult to reach. But, after reaching customer service, issue was resolved without a problem.

I hope the product is as good as the speed I received the item. I even made a mistake on my order, and it still arrived fast. Thanx, will do business with again.

Excellent low price, super fast shipping, and great communication. Top notch seller. Recommend highly!!
