Vulcan C/R Head Gasket GM LS 4.056 x .059

The SCE Gaskets Vulcan C/R Head Gasket for GM LS 4.056 x .059 is a precision-engineered cylinder head gasket designed to deliver reliable sealing under the demanding conditions of high-performance LS engine builds. Built with a steel core laminate construction, this Vulcan cut-ring gasket provides superior durability and compression consistency across the entire bore diameter, making it the choice for both street and race applications where dependable combustion chamber sealing is non-negotiable.

The 4.056-inch bore specification matches the standard displacement range of LS blocks used in muscle cars, trucks, and performance platforms, while the 0.059-inch compression thickness is calibrated to maintain optimal gasket load and sealing pressure throughout the engine's operating envelope. Steel core laminate construction resists deformation under repeated thermal cycling and maintains flatness under high combustion pressures. The cut-ring design reduces friction loss and maximizes gasket life compared to standard reinforced gaskets, delivering consistent sealing performance through multiple heat cycles.

This gasket is engineered for LS-series engines across the GM lineup—including LS1, LS2, LS3, LS7, and LS9 variants—making it essential for rebuilds, performance upgrades, and engine swaps where OEM specifications must be matched exactly. Whether assembling a 5.3L truck engine, a 6.0L performance build, or a 7.0L crate engine, the Vulcan C/R gasket delivers the precision fit and compression characteristics required for trouble-free operation. SCE Gaskets has built a reputation among engine builders and performance shops for manufacturing gaskets that survive the harshest conditions without compromise.
