The Cometic intake gasket kit for Oldsmobile 400/425/455 (.060 in) with 2.490" x 1.410" rectangular ports is manufactured for stock and high-demand applications. AFM construction—a nitrile compound bonded to an aluminum core—offers temperature resistance above 250°F, strong torque retention and 85% recovery, so the gaskets typically do not require sealers or re-torquing. Cometic produces these kits to meet or exceed OEM quality.
