Intake Manifold Gasket

The Intake Manifold Gasket (Ford M-9439-A50) is a precision OEM-equivalent replacement component designed for Small Block Ford engines requiring reliable seal integrity at the intake manifold-to-cylinder head interface. This gasket is engineered for operators and technicians who demand factory-level performance and durability when servicing Ford powerplants in field, shop, or competition environments. Proper intake manifold sealing is critical to preventing coolant leaks, air ingestion, and combustion gas bypass—all of which degrade engine reliability and efficiency.

This gasket features a steel core laminate construction with a nominal thickness of 0.065 inches, providing robust structural support and controlled compression set under thermal cycling. The rectangular port design accommodates 1.302 by 2.2 inch port geometry, ensuring precise alignment and uniform sealing pressure across the entire interface. Steel core laminate construction resists blowout, maintains dimensional stability across temperature extremes typical of engine operation, and provides superior reusability compared to single-layer alternatives. The controlled material density prevents over-compression while maintaining seal conformity to both cast iron and aluminum mating surfaces.

Field technicians, engine builders, and preventive maintenance teams benefit most from this OEM-specification replacement, particularly during head gasket services, engine rebuilds, or coolant system repairs. Installation is straightforward: verify mating surface cleanliness, position the gasket on the cylinder head with port alignment pins or studs as guides, and torque the manifold to Ford specifications. Compatible with all Small Block Ford applications using this port configuration, this gasket delivers the seal reliability expected from factory engineering without premium pricing. Single gasket sold per unit; order quantity reflects individual gasket count.
