Product Details

The Cometic C5434-060 is a multi-layer steel (MLS) cylinder head gasket engineered for high-performance Chevrolet Mark-IV and GM Gen-V/VI Big Block V8 engines. This precision gasket features a .060" compressed thickness and is designed for a 4.630" bore diameter, making it ideal for custom engine builds and performance applications.

Key Features:

  • Multi-layer steel construction provides superior sealing and durability under extreme cylinder pressures
  • 4.630" bore diameter accommodates standard and modified big block configurations
  • .060" compressed thickness allows for precise compression ratio tuning
  • Undersized water ports enable custom port matching and coolant flow optimization
  • Designed specifically for aftermarket cylinder heads with flexibility for customization
  • Compatible with Chevrolet Mark-IV, Gen-V, and Gen-VI big block V8 platforms

Cometic MLS gaskets utilize multiple layers of stainless steel with advanced coating technology to maintain seal integrity through extreme heat cycling and combustion pressures. The undersized water port design gives engine builders the freedom to machine ports to their exact specifications, ensuring perfect alignment with both block and head castings for optimal coolant distribution.

I was having difficulty finding EGR Fender Flares that were available, but Autoplicity not only had the exact set I needed but had them at the lowest price I'd seen and had super fast shipping - thank you Autoplicity!

Autoplicity has great prices and quality products for sale, I'd give it 1/2 star less for slow shipping given the option. Took a while to get out their door, regardless, I would still purchase again, thanks Autoplicity!

Best price around and good service.

Delay with the shipping, still haven't received item. Great price if I ever receive the item.

Had a problem but they fixed it. Fast shipping.

No hassle ordering and fast quality shipping at a reasonable price

Loved ordering from Autoplicity. Was the cheapest price around and best quality. Will be ordering again in the near future.
