240-300 Ford Head Gasket INLINE 240 300 ENG 65-87

The 240-300 Ford Head Gasket INLINE 240 300 ENG 65-87 is a critical OEM-specification replacement cylinder head gasket engineered for Ford's legendary inline-6 engine platform spanning the 1965 to 1987 model years. Whether you're rebuilding a classic pickup, restoring a vintage truck, or maintaining an older work vehicle, this FEL-PRO gasket delivers the sealing integrity necessary to prevent coolant and oil leakage at the cylinder head-to-block interface. Head gasket failure is one of the most costly engine problems a technician encounters, making the choice of replacement gasket material and design absolutely essential for long-term reliability.

This FEL-PRO head gasket features a steel core laminate construction with 0.039-inch compression thickness and a 4.180-inch bore diameter, precisely matching factory specifications for the Ford inline-6 engine family. The steel core laminate design provides superior strength and heat resistance compared to pure asbestos or fiber gaskets, preventing blowout under high combustion pressures and thermal cycling. The 0.039-inch thickness ensures proper compression ratio maintenance and valve timing geometry—critical factors that directly impact engine performance, fuel economy, and emissions control. FEL-PRO's manufacturing standards guarantee consistent material density and surface finish, reducing the risk of micro-leaks that can compromise engine longevity.

Mechanics and restoration enthusiasts trust FEL-PRO head gaskets for their durability across the entire Ford inline-6 range, from the 240 cubic-inch to 300 cubic-inch displacement variants. Installation requires proper head bolt torque sequencing and cylinder head surface preparation—both critical to gasket seating and long-term performance. This single gasket (sold individually) fits 1965 through 1987 Ford vehicles equipped with the inline-6 engine, making it an indispensable component for any engine rebuild, overhaul, or head removal service. Proper installation ensures a reliable seal for thousands of miles of trouble-free operation.
