Product Details

The Cometic C5432-120 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Mark-IV and GM Gen-V/VI Big Block V8 engines. This precision gasket features a .120" (120 thousandths) compressed thickness and is designed for a 4.310" bore diameter, making it ideal for performance builds and custom engine applications.

Key Features:

  • Multi-Layer Steel construction for superior sealing and durability under high compression and extreme temperatures
  • 4.310" bore diameter accommodates various big block configurations
  • .120" compressed thickness provides optimal sealing with aftermarket cylinder heads
  • Undersized water ports allow for custom porting and coolant passage optimization
  • Designed for use with aftermarket performance heads on Mark-IV, Gen-V, and Gen-VI big block engines
  • Cometic's MLS technology ensures excellent combustion sealing and resistance to gasket failure

The undersized water port design gives engine builders the flexibility to match coolant passages precisely to their specific cylinder head and block combination, eliminating the risk of gasket overhang into water jackets. This gasket is an excellent choice for serious performance applications where reliability and custom fitment are essential.

<br><br>Borgeson 000940<br><br>I found Autoplicity during a price search on the Borgeson steering shaft for my truck. I had never heard of them, and was a bit skepticle. But after doing some research, found that Autoplicity has a good reputation on a Jeep forum I visit.<br><br>I decided to order, and I am impresed. Extremely fast shipping, I placed my order on Saturday, and its now Monday before noon. I am holding the new part!
