Aluminum Cyl. Head Chevy Intake Gasket

The Aluminum Cyl. Head Chevy Intake Gasket by FEL-PRO is a critical OEM-specification replacement component engineered for small-block Chevrolet engines with 18-degree cylinder heads. This intake manifold gasket serves as the primary seal between the intake manifold and cylinder head, preventing vacuum leaks, coolant seepage, and combustion gas bypass that compromise engine efficiency and reliability. Whether you're rebuilding a classic muscle car, restoring a performance engine, or maintaining fleet vehicles, this gasket is essential to restore proper engine breathing and thermal management.

Manufactured from composite material with a precise 0.12-inch thickness, the Aluminum Cyl. Head Chevy Intake Gasket features a 1.31 x 2.02-inch rectangular port design that matches factory specifications for small-block Chevy applications with 18-degree heads. The composite construction balances durability with conformability, allowing the gasket to seat evenly across the manifold surface and withstand thermal cycling without degradation. FEL-PRO's engineering ensures zero-leak performance under normal operating temperatures and pressure, preventing the vacuum leaks that typically cause rough idle, hesitation, and increased emissions in aging or rebuilt engines.

Technicians and engine builders rely on the Aluminum Cyl. Head Chevy Intake Gasket for any small-block Chevy rebuild or top-end service involving intake manifold removal. Installation is straightforward during standard manifold gasket replacement—simply remove the old gasket, clean the mating surfaces thoroughly, and position the new gasket before torquing the manifold bolts to specification. This product is specifically designed for small-block Chevrolet engines equipped with aluminum cylinder heads featuring 18-degree port angles, ensuring proper fit and reliable sealing for street engines, race builds, and marine applications alike.
