Product Details

The Cometic C5434-036 is a multi-layer steel (MLS) cylinder head gasket engineered specifically for Chevrolet Mark-IV and GM Gen-V/VI big block V8 engines. This precision-manufactured gasket features a .036" compressed thickness and is designed for a 4.630" bore diameter, making it ideal for performance and racing applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability under high cylinder pressures
  • .036" compressed thickness provides optimal sealing with modern engine builds
  • 4.630" bore diameter accommodates standard and performance big block configurations
  • Undersized water ports allow for custom port matching and coolant flow optimization
  • Designed for aftermarket cylinder heads with customizable water jacket configurations
  • Exceeds OEM specifications for strength and heat resistance

Cometic's MLS gaskets feature multiple layers of stainless steel with a polymer coating that provides micro-sealing capabilities while maintaining the strength needed for high-performance and forced induction applications. The undersized water ports give engine builders the flexibility to match-port the gasket to their specific cylinder head and block combination, optimizing coolant flow for maximum thermal efficiency.

My name is Doug Raber and I tell you the truth when I say autoplicity is a great site to shop for auto parts. The prices are low and the customer service is excellent.

Excellent price on the product and shipping! Ordered on Thursday night (after they closed) and they were shipped out Monday!

First time I've tried these guys. Had trouble getting this product from my normal source (backordered) but Autoplicity shipped quickly and had a better price too! You know I will be back! Thanks!

Great customer service. Prompt shipment and excellent prices. I will defiantly be ordering from them again. Just wish I would have found them sooner!!

Great price, fast shipping and the items was correct. A perfect transaction. Thank you!
