Cometic HTS exhaust manifold gasket set for Chevrolet Mark‑IV and GM Gen‑V/VI Big Block V8 (.060in) uses a graphite/fiber blend mechanically bonded to a perforated stainless steel core for high‑temperature sealing without sealants. The construction tolerates varied head and manifold combinations and provides compressibility for sealing imperfect surfaces while resisting corrosion and maintaining clamp load stability.
