SCE Gaskets CR200559 Vulcan Cut Ring Head Gasket Bore Thick GM LS - 4.056 0.059

The SCE Gaskets CR200559 is a high-performance Vulcan Cut Ring cylinder head gasket engineered specifically for GM LS-Series engines. This precision-manufactured gasket features a 4.056-inch bore diameter and 0.059-inch compression thickness, making it ideal for performance builds requiring precise combustion seal and compression control.

Key Features:

• Vulcan Cut Ring design provides superior combustion sealing at the critical bore area
• Composite construction with stainless steel fire ring for durability and heat resistance
• 4.056-inch bore diameter accommodates standard and slightly overbored LS blocks
• 0.059-inch compressed thickness allows precise compression ratio tuning
• Compatible with all GM LS-Series small block engines including LS1, LS2, LS3, LS6, and LS7
• Multi-layer steel (MLS) alternative for street and competition applications

SCE Gaskets' Vulcan Cut Ring technology features a stainless steel fire ring that is precisely cut and embedded into the composite gasket material, creating an exceptional seal around each cylinder bore. This design is particularly effective in high-performance applications where cylinder pressure and combustion temperatures are elevated. The composite base material provides excellent conformability to deck surfaces while maintaining long-term durability.
