The graphite core has excellent thermoconductivity (transfers heat) away from hot spots in head preventing gasket burn-out. They provide excellent stability, compressibility and high temperature endurance. A high temperature silicone coating ensures sealing of engine fluids. Compatible with cast iron or aluminum heads, they will not brinell (indent) aluminum cylinder heads. Suitable for high performance street, drag race and oval track use. Sold individually.
