Chevy BBC 454 Gen 5 & 6 1991 - Up 1Pc RMS Rubber Oil Pan Gasket
PCE gaskets are designed for today's performance engines, which can create excessive amounts of vacuum and pressure in the oil pan. They're constructed from a cellulose/nitrile material that features excellent tensile strength and superior blowout resistance, and their latex coating conforms to minor sealing-surface irregularities for a better seal.
