The Cometic Pontiac 326/350/389/400/421/428/455 V8 .030in MLS Exhaust Manifold Gasket Set - C5905-030 is a precision-engineered exhaust gasket with a compressed thickness of .030".
Cometic Multi-Layer Steel (MLS) exhaust gaskets are built to withstand the extreme heat and pressure cycles of high-performance exhaust systems. Featuring Multi-Layer Steel (MLS) construction, this gasket uses multiple embossed steel layers that conform to surface irregularities and maintain a positive seal. Designed to seal flanged connections between the exhaust manifold/header and the cylinder head or down-pipe, these gaskets prevent exhaust leaks that rob power and cause drone.
