SCE GR Supra B58 Vulcan Cut-Ring Head Gasket

Overview

The SCE Gaskets Vulcan Cut-Ring Head Gasket is engineered for serious performance engines that demand superior sealing under extreme conditions. This hybrid head gasket combines advanced materials and design features to deliver outstanding durability, leak resistance, and combustion sealing compared with traditional composite or multi-layer steel (MLS) gaskets.

High-Performance Seal Design

Crafted with a pliable, perforated metal-core composite gasket body, this head gasket provides exceptional sealing for coolant and oil passages without the need for additional sealants. Around each cylinder bore are solid stainless steel cut-rings, which “bite” into the cylinder head surface to form a positive mechanical seal against combustion pressure leakage — improving reliability in high-compression and forced-induction applications.
