Product Details

The Cometic C5817-027 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for GM Generation V and Generation VI Big Block V8 engines. This precision gasket features a 4.320-inch bore diameter and a compressed thickness of .027 inches, providing an optimal seal between the cylinder head and engine block.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 4.320-inch bore diameter designed for GM Gen V/VI Big Block V8 applications
  • .027-inch compressed gasket thickness
  • Engineered to withstand extreme temperatures and pressures in high-performance applications
  • Provides excellent conformability to cylinder head and block surfaces
  • Resists gasket failure from cylinder pressure and head lift

Cometic's MLS gaskets feature multiple layers of stainless steel with specialized coatings that ensure proper sealing while accommodating engine movement and thermal expansion. This gasket is ideal for performance builds, racing applications, and engine rebuilds where reliability and consistent sealing are critical.

I was very surprised that even with shipping, I saved 40% over the exact same item at a local auto store. They shipped the next business day and I am expecting to receive within 1 week of placing the order.<br>Autoplicity's website is easy to navigate and the selection and prices are top notch. I will be ordering from here again!

Fast shipping, good communication, a pleasure to do business with. I would definitely buy from again.

Fast, with great prices. I would definitely buy from Autoplicity again.
