Intake Manifold Gasket Facing (Shim) Set of 4 Big Block .015

MMR-1162  Intake Manifold Gasket Facing (Shim) Set of 4 Big Block .015 Made from .015" thick gasket facing material, these feature the standard 2.27" tall by 1.23" wide port openings and are sold in a set of 4. They are designed to work with the factory replacement type "bathtub" steel valley pans listed on our gaskets page. We recommend using one gasket on either side of the port area of the valley pan to aid in sealing, and to allow for the expansion and contraction of aluminum intake manifolds. These interchange with MMR-0805. These can also be used as standard intake gaskets with aftermarket style valley pans if the .015" material is preferred.
