Cometic C15716-054 Dart Hemi Gen3 Iron Eagle Block .054in MLX Cylinder Head Gasket 4.100in Bore RHS

The Cometic C15716-054 is a .054" MLX (Multi-Layer Xtreme) cylinder head gasket designed for the Dart Gen 3 Hemi Iron Eagle block with a 4.100" bore, right-hand side (RHS) orientation. Built for high-performance and racing applications, this gasket delivers superior combustion sealing reliability under extreme cylinder pressure.

Key Features:

• MLX Multi-Layer Xtreme construction — features an integrated stopper fold-over layer for enhanced combustion chamber sealing and improved clamp load around the cylinder bore
• 5-layer stainless steel design — multiple embossed stainless steel layers provide exceptional rebound, strength, and corrosion resistance
• Viton-coated outer layers — embossed outer layers are coated with Viton fluoroelastomer rubber, heat resistant to 250°C (482°F), conforming to a wide range of surface finishes and sealing conditions
• Reduced bore distortion — improved clamp load distribution around the cylinder without adding unwanted bore distortion
• .054" compressed thickness — precise thickness for accurate compression ratio tuning on the Dart Iron Eagle block platform
• 4.100" bore size — matched to the Iron Eagle block bore specifications
• Right-Hand Side (RHS) orientation — designed for proper fitment on the correct cylinder bank

Cometic MLX head gaskets are the preferred choice for serious engine builders using aftermarket blocks like the Dart Iron Eagle, where high boost, nitrous, or forced induction demands a gasket that goes beyond OEM tolerances. The stopper layer technology prevents combustion seal yielding even under extreme clamping loads, making this gasket ideal for street/strip and all-out race builds.
