Vulcan C/R Head Gasket GM LS 4.150 x .059

The Vulcan C/R Head Gasket GM LS 4.150 x .059 from SCE Gaskets is engineered for serious LS-series engine builders and high-performance mechanics who demand reliability under extreme conditions. This cut-ring cylinder head gasket is the critical seal between your block and head, preventing combustion leakage and coolant bypass—failures that can destroy an engine in seconds. Whether you're building a naturally aspirated stroker, forced-induction platform, or street/strip combination, a quality head gasket is non-negotiable for longevity and consistent power delivery.

The Vulcan C/R designation indicates SCE's proprietary Vulcan cut-ring design paired with a steel core laminate construction. The 4.150-inch bore specification matches modern LS platforms and large-displacement variants, while the 0.059-inch compression thickness is calibrated to maintain proper combustion chamber volume and peak cylinder pressure. Cut-ring technology features a precise elastomer-coated steel ring that seats against the combustion chamber perimeter, eliminating hot-spot leakage that plagues conventional MLS gaskets in forced-induction applications. Steel core laminates resist the thermal cycling and pressure spikes inherent to turbocharged, supercharged, and high-RPM naturally aspirated builds, making this gasket suitable for both street and competition environments.

LS engine enthusiasts tackling rebuild, stroker, or upgrade projects will find this gasket essential for any power level above stock. The 4.150-inch bore accommodates LS3, LS7, LSA, and common 427–454 cubic-inch builds, making it a versatile choice for both crate-engine swaps and bespoke machine-shop builds. Installation requires standard clean-deck procedures: proper head and block surface finish, correct head-bolt torque sequence, and alignment with ARP or OEM fastener specifications. Pairing the Vulcan C/R Head Gasket with quality fasteners and precision machine work ensures a durable seal that handles repeated power cycles, boost events, and thermal stress for thousands of miles.
