Cometic C15714-054 Gen 3 Hemi DART Block 4.150" Bore .054" MLX Cylinder Head Gasket RHS

The Cometic C15714-054 is a Multi-Layer Steel (MLX) Cylinder Head Gasket designed for Gen 3 Hemi engines built on the Dart block platform. Featuring a 4.150" bore and .054" compressed thickness, this is the Right Hand Side (RHS) gasket engineered for high-performance and race applications demanding superior sealing integrity.

Key Features:

• Multi-Layer Steel (MLX) construction — multiple embossed layers of proprietary high-temperature coated and uncoated stainless steel for maximum strength and durability
• Viton fluoroelastomer coating on outer layers, heat-resistant and engineered to handle demanding sealing conditions, varied load situations, and a wide range of surface finishes
• Active combustion and water/oil seals on outer layers provide comprehensive engine sealing in one gasket
• Stopper-style bore seal — uncoated stainless shim layer folds back on itself to form a robust locking bore seal
• 4.150" bore diameter for Gen 3 Hemi Dart block applications
• .054" compressed thickness for precise compression ratio tuning
• Right Hand Side (RHS) — sold individually; pair with C15715-054 (LHS) for a complete set
• Corrosion-resistant stainless steel alloy materials selected for tensile strength and longevity
