Product Details

The Cometic C5761-140 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for GM L18 Vortec 8100 Gen-VII Big Block V8 engines. This high-performance gasket features a 4.280-inch bore diameter and .140-inch thickness, providing superior sealing and durability in demanding applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for maximum sealing performance and durability
  • 4.280-inch bore diameter for precise fitment on Vortec 8100 engines
  • .140-inch (3.56mm) compressed thickness for optimal compression ratio control
  • Engineered for right-hand side (RHS) cylinder head applications
  • Superior resistance to extreme temperatures and combustion pressures
  • Eliminates the need for additional sealants or re-torquing

Cometic's MLS gaskets feature multiple layers of stainless steel with a Viton rubber coating, allowing them to conform to minor surface imperfections while maintaining exceptional blowout resistance. This gasket is ideal for stock rebuilds, performance upgrades, and forced induction applications on GM's 8.1L (496ci) big block V8 engines found in heavy-duty trucks, motorhomes, and marine applications.

In a rush to get my car up and running, Autoplicity had the best price on the items I needed, and in stock as well as shipped quickly. Just what I was looking for, thanks!

Great price. Minor problems with shipping because of UPS (dropped box and broke part, late delivery). Autoplicity sending me out replacement part.
