- Premium Copper-Clad Cylinder Head Gasket Construction – Delivers superior heat conductivity to pull heat away from the combustion chamber, helping prevent hot spots, warping, and premature gasket failure.
- Exceptional Strength & Durability – Copper’s high tensile strength and elasticity stand up to high cylinder pressures and thermal cycling far better than standard composite gaskets.
- Malleable for a Tight, Reliable Seal – Soft copper conforms to minor surface imperfections on the block and head for excellent combustion sealing and reduced blow-by.
- Corrosion-Resistant Design – Resists degradation from coolant, oil, and combustion byproducts better than many traditional gasket materials, extending service life.
- Ideal for Restorations & Heavy-Duty Use – Popular choice for classic restorations and pulling rigs.
