Intake Gasket - BBC w/SR 20 Heads .120 Thick Ea.

The Intake Gasket – BBC w/SR 20 Heads .120 Thick is engineered for Big Block Chevy engines paired with Brodix SR20 cylinder heads, delivering the precision seal required in high-performance and race applications. This gasket bridges the critical interface between your intake manifold and heads, preventing coolant and combustion gas leakage that can compromise engine efficiency and reliability. Mechanics and engine builders trust Brodix gasket specifications for their dimensional accuracy and material durability, especially in modified and boosted builds where peak cylinder pressure demands a fail-proof seal.

At .120 inches thick, this gasket provides the correct compression height for SR20 head geometry, ensuring proper intake port alignment and manifold seating without distortion. Brodix manufactures to tight tolerances, utilizing quality facing materials and reinforced design to withstand thermal cycling and vibration inherent to aggressive engine operation. The precise thickness specification is essential—too thin and you risk port misalignment; too thick and you compromise plenum volume and port flow characteristics. This gasket performs reliably across naturally aspirated, supercharged, and turbocharged Big Block applications where consistency matters.

Builders restoring, tuning, or assembling BBC/SR20 combinations—whether for street machines, race engines, or marine powerplants—depend on this gasket for leak-free assembly and long-term durability. Installation is straightforward: position the gasket on cleaned head surfaces before manifold installation, and torque per your engine's specification sheet. One gasket per purchase; order the quantity matching your manifold's port count. Keep extras on hand for future rebuilds, as proper gasket replacement during any intake work prevents costly coolant loss and maintains peak combustion efficiency.
