SBC SB2 Intake Gasket .045in Thick

The FEL-PRO SBC SB2 Intake Gasket .045in Thick is the factory-engineered solution for sealing your small-block Chevy intake manifold to the cylinder head. Built for Chevy small-block applications, this composite gasket pair maintains reliable compression and prevents coolant or oil seepage at the intake interface—a critical junction where temperature cycling and vibration test even the best gasket materials. Whether you're rebuilding a classic 350, refreshing a tired 327, or assembling a modified engine, proper intake gasket selection directly impacts combustion efficiency and prevents costly head gasket failure downstream.

FEL-PRO's .045-inch thickness specification strikes the ideal balance between conformability and structural integrity on modern small-block heads and manifolds. The composite material construction resists fuel, oil, and coolant degradation while accommodating the micro-irregularities in cast iron surfaces without requiring extreme clamping force. Each gasket in this pair features precision-cut 1.52 x 2.07-inch rectangular ports that align exactly with SBC port geometry, ensuring unobstructed flow to cylinder one through eight and eliminating flow restriction that can rob horsepower or create lean spots during tuning. The gasket's ability to maintain seal integrity across repeated heat cycles—especially during aggressive driving or boosted applications—makes it the trusted choice for both stock restorations and high-output builds.

Serious small-block enthusiasts and professional engine builders rely on this gasket when precision matters: manifold re-gasketings after carburetor or fuel-injection conversions, post-machine-shop assembly, or preventive maintenance on higher-mileage engines. Installation is straightforward—clean the mating surfaces to bare metal, set the gasket pair dry (FEL-PRO composites do not require sealant), torque the manifold fasteners in a star pattern to OEM spec, and verify no coolant weeping after warm-up. Compatible with all factory and aftermarket intake manifolds designed for small-block Chevy applications, this gasket pair delivers the sealing performance that keeps your build leak-free and your tune dialed in.
