SBC 18 Deg. w/ Adapter p late EXH gasket

The SBC 18 Deg. w/ Adapter Plate EXH gasket from FEL-PRO is a purpose-engineered exhaust manifold gasket designed for Small Block Chevy engines equipped with 18-degree cylinder heads and adapter plate configurations. This gasket is essential for anyone building or rebuilding a classic or modern SBC engine, whether for street performance, restoration, or racing applications. Proper sealing at the exhaust port interface prevents costly exhaust leaks, manifold warping, and performance loss that plague inferior gasket materials.

Constructed with a steel core laminate design, the SBC 18 Deg. w/ Adapter Plate EXH gasket features 2.000-inch round port openings and is precision-engineered to match the specific port geometry of 18-degree small block heads. The steel core laminate construction provides superior heat resistance and durability compared to composite-only gaskets, maintaining a reliable seal under extreme combustion pressures and thermal cycling. The adapter plate configuration allows seamless integration with modern header or manifold systems while accommodating variations in mounting surface flatness, a critical factor for preventing blow-by and maximizing combustion efficiency.

Mechanics and engine builders working on SBC platforms—from restoration shops to high-performance shops—rely on FEL-PRO's precision gaskets to eliminate leak-prone connections between heads and exhaust manifolds. The pair configuration ensures both sides of the engine are sealed with matched components, critical for balanced exhaust flow and consistent engine performance. Installation is straightforward: position the gaskets on the exhaust ports with the steel core facing the manifold, torque fasteners to OEM specifications, and verify no movement occurs during the first heat cycle. Compatible with all standard SBC 18-degree head applications using adapter plate mounting systems.
