Cometic's header collector gasket set (0.040" aluminum; 2.5" diameter port; 3.5" bolt circle) is designed for use with manifolds or headers and created to seal exhaust flanges without messy sealants. It resists burning through or pushing out under extreme cylinder pressures, maintains torque set between flanges, and offers corrosion resistance for varied head and manifold material combinations to prevent exhaust leaks.
