Product Details

The Cometic C5447-140 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chrysler Gen-2 Hemi engines. This precision-manufactured gasket features a 4.500-inch bore diameter and .140-inch compressed thickness, making it ideal for both stock and performance engine builds.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior strength and durability
  • 4.500-inch bore diameter accommodates standard and mild overbore applications
  • .140-inch compressed thickness for precise compression ratio tuning
  • Designed specifically for Chrysler Gen-2 Hemi engines (5.7L, 6.1L, 6.4L platforms)
  • Advanced material composition ensures excellent sealing under extreme cylinder pressures
  • Resists warping, corrosion, and combustion gas leakage

Cometic's MLS head gaskets feature multiple layers of stainless steel with proprietary coatings that maintain seal integrity through repeated heat cycles. The embossed sealing beads provide even loading around combustion chambers, coolant passages, and oil return holes. This gasket is an excellent choice for performance rebuilds, turbo/supercharged applications, and engines running elevated boost or compression levels.
