The Cometic CFM exhaust manifold gasket kit for Oldsmobile 371 Gen-1 Rocket V8 (.059" thickness) is built to seal high-pressure exhaust ports. The J-2 Golden Rocket kit uses a perforated galvanized steel core with asbestos-free fiber applied both sides, intended for extreme cylinder pressures. It resists corrosion, maintains torque set, and is formulated to avoid burn-through or push-out between differing head and manifold materials.
