Intake Manifold Gasket Set (Shims) Big Block

MMR-0805  Intake Manifold Gasket Set (Shims) Big Block

Used best with valley pan with imperfect or uneven surfaces

Made from .030" 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. 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.
