The Cometic valve cover gasket set for Chevrolet Gen-1 Small Block V8 (18/23 degree heads) is a .188in fiber seal built to outperform cork or paper gaskets. Race-inspired materials and a steel torque-limiting frame resist blowouts, over‑tightening and high vacuum. Fully cured nitrile butadiene rubber provides strong fluid resistance and excellent sealability across varied flange conditions.
