The Cometic fiber intake manifold gasket set for Chevrolet Gen‑1 Small Block V8 (.020 in) fits 1.245" x 1.980" rectangle port, 23° heads with exhaust crossover. It uses AFM construction—nitrile synthetic rubber bonded to an aluminum core—for temperature resistance over 250°F and strong fluid resistance. AFM maintains torque retention and recovery, requires no sealants or re-torque, and provides excellent sealing across varied flange conditions.
