SB Chevy Intake Gaskets 262-400 ENGINES

The SB Chevy Intake Gaskets 262-400 ENGINES by FEL-PRO are essential OEM-quality sealing components designed for small-block Chevrolet engines ranging from 262 to 400 cubic inches. Whether you're restoring a classic Chevy, rebuilding a tired 350, or freshening up intake manifold seals on a 327, these gaskets prevent coolant and oil leakage at the critical intake manifold-to-head interface. Engine builders and DIY mechanics rely on FEL-PRO's reputation for precision fitment and durability when air and fuel mixture integrity matters most.

These intake manifold gaskets feature a composite Printoseal construction 0.06 inches thick, engineered to handle the thermal cycling and pressure variations inherent in small-block Chevy performance. The rectangular port design accommodates 1.38 x 2.38 inch openings, matching OEM intake manifold specifications across the 262–400 displacement range. Composite material provides superior sealing consistency compared to cork or paper alternatives, resisting oil degradation and maintaining compression seal integrity across extended driving cycles and higher RPM operation. The lightweight kit (0.3 lbs) ships compact but delivers professional-grade sealing performance.

Engine enthusiasts rebuilding 350, 327, 283, or 400 small-block variants benefit most from this complete gasket set, as proper intake sealing eliminates hard-to-diagnose coolant seeps and oil weeping that develop after years of use. Installation is straightforward—remove the old gaskets, clean the mounting surfaces thoroughly, and seat the new composites dry or with light gasket sealant, depending on manifold condition. These gaskets are compatible with stock and performance intake manifolds across all SB Chevy generations, making them indispensable for any serious engine work or preventive maintenance on carbureted or fuel-injected platforms.
