The FLANGE SBC 2in ROUND SB2 -- 5/16 is a precision exhaust flange designed for small-block Chevrolet engines seeking reliable header-to-manifold connections. This component serves builders, restoration specialists, and performance enthusiasts who require OEM-quality flanges for custom exhaust system assembly. Built by Schoenfeld, a trusted name in exhaust engineering, this flange ensures proper sealing and structural integrity in high-temperature exhaust environments where leak-free operation is non-negotiable.
The 2-inch round design accommodates standard header tube diameters while the 5/16-inch bolt hole spacing aligns with common SBC bolt patterns used on both street and race applications. Its flanged construction distributes clamping load evenly, reducing the risk of warping or gasket failure under thermal cycling. Manufactured to tight tolerances, the flange resists corrosion and maintains dimensional accuracy through repeated heat cycles, critical for engines operating at elevated temperatures where expansion and contraction stress fastening systems.
This flange is ideal for SBC engine builders assembling custom headers, intake manifolds, or turbo applications requiring precise exhaust port matching. Installation requires careful alignment with corresponding ports and use of quality gasket material to maximize sealing effectiveness. The compact 3.55-inch length and lightweight 1.24-pound specification make it easy to handle during assembly while maintaining the rigidity needed for long-term reliability in both naturally aspirated and forced-induction setups.
