Product Details

The Cometic C5645-045 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for GM LT1 and LT4 Generation 2 small block V8 engines. This gasket features a 4.040-inch bore diameter and a compressed thickness of .045 inches, providing exceptional sealing performance for stock and modified applications.

Key Features:

  • Multi-Layer Steel construction for superior combustion sealing and durability
  • 4.040-inch bore diameter fits LT1/LT4 Gen-2 small block V8 engines
  • .045-inch compressed thickness for precise compression ratio tuning
  • Exceeds OEM specifications for reliability in performance applications
  • Advanced material technology provides excellent recovery and torque retention
  • Resistant to extreme temperatures and pressures

Cometic MLS head gaskets incorporate multiple layers of stainless steel with specialized coatings that allow the gasket to conform to imperfections in the sealing surface. This design ensures a reliable seal in both stock rebuilds and high-performance builds where cylinder pressures and temperatures exceed factory specifications.

So far, so good. As long as there aren't multiple delays in shipping as I experienced with a competitor, before I found Autoplicity, then this will continue to be a 5 Star. Thanks.

I ordered an Optima battery for my truck after I did a Google search for the battery. Autoplicity was the cheapest on the Web. Even cheaper then eBay. They got me hooked. Thanks Autoplicity
