Big-block Chevy oil-pan gaskets are not universal. Mark IV engines use a different rear main seal and rail arrangement from Mark V and Gen VI engines, and a stock-style pan can need a different gasket from a race or stroker pan. Match the engine generation, pan manufacturer, pan rail, dipstick provision and crank clearance before ordering.
