The Cometic Dart Hemi Gen3 Iron Eagle Block .063in DST Cyl. Head Gasket - 4.275in Bore - LHS - C15736-063 is a precision-engineered head gasket with a 4.275" bore and .063" compressed thickness for the Left-Hand Side (LHS).
The Cometic Dynamic Seal Technology (DST) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short. Featuring Dynamic Seal Technology (DST) construction, this gasket uses a proprietary multi-layer design with an elastomeric sealing bead that provides consistent clamp load retention. Precision CNC-machined to exacting tolerances, this gasket seals combustion, water jackets, and oil passages simultaneously — eliminating the need for multiple gaskets or sealing compounds.
