Intake Manifold Gasket RB Big Block Valley Pan Blocked Crossover
MMR-1191 Intake Manifold Gasket RB Big Block Valley Pan Blocked Crossover
Stainless Intake Valley Pan Gasket - RB Engine - BLOCKED Exhaust Crossover
Stainless Steel eliminates all corrosion issues, and looks great as well! These fit "RB" (413/426/440) engines. We recommend using these with our part # MMR-1162 intake "facing" gaskets. This version features the center hole for the exhaust heat crossover BLOCKED, which is great for performance engines when you don't want the extra heat from the exhaust crossover circulating below the intake manifold.
