BBC Intake Gasket 1.750 x 2.500

The BBC Intake Gasket 1.750 x 2.500 by SCE Gaskets is purpose-built for Big Block Chevy engine platforms requiring a reliable, OEM-level intake manifold seal. This gasket addresses a critical vulnerability in high-performance and stock BBC applications: manifold creep and coolant leakage at the intake-to-block interface. Whether you're rebuilding a crate engine, restoring a classic muscle car, or maintaining fleet equipment, a quality intake gasket is non-negotiable for preventing costly coolant loss and internal corrosion.

Manufactured from composite silicone material with a precision thickness of 0.062 inches, the BBC Intake Gasket delivers superior sealing integrity across repeated thermal cycles. The 1.75 x 2.55 inch rectangular port configuration matches OEM specifications for Big Block Chevy manifolds, ensuring proper alignment and load distribution across the gasket face. Silicone composite construction provides excellent resistance to coolant additives, oil vapor, and temperature fluctuations—critical factors in maintaining a hermetic seal without degradation over thousands of miles of operation.

Technicians and engine builders specify SCE gaskets for BBC applications because the material resists compression set and maintains conformability under load. This gasket pair fits all Big Block Chevy engines (427, 454, 502 displacements) and is compatible with both cast-iron and aluminum intake manifolds. Installation requires only standard gasket surface preparation—clean, dry surfaces free of old gasket debris—and proper manifold bolt torque sequencing. Replace both intake gaskets simultaneously to ensure matched compression and uniform sealing geometry.
