The Cometic ArmorCore exhaust manifold gasket set for Chevrolet Mark-IV big block V8s is .064" thick and intended for Brodix Race-Rite and related Big Brodie heads. Armor Clad construction tolerates extreme exhaust temperatures (up to 2000°F) and compresses to seal imperfect flange surfaces. The gaskets resist burn-through, maintain torque retention, and handle high cylinder pressures encountered in race applications.
