GM 2.4L Ecotec Direct Injection Cylinder Head – Casting #279

Brand New Casting – Fully Loaded with Cams, Lifters, and Rockers

Heavy Duty Parts Company is proud to offer this premium, all-in-one replacement solution for the GM 2.4L DOHC Ecotec engine series. Engineered for superior longevity, this is a brand-new aftermarket casting specifically developed to exceed original equipment (OE) dimensional tolerances. Unlike remanufactured units that may have already undergone multiple thermal cycles, this “zero-hour” head provides a fresh structural foundation, eliminating the risks of previous fatigue or micro-cracking common in high-mileage aluminum castings.

This cylinder head arrives as a comprehensive, “out-of-the-box” solution, significantly reducing installation downtime and labor costs. It is delivered fully loaded and pre-assembled with a complete valvetrain, including precision-seated valves, calibrated springs, camshafts, lifters, and rocker arms. Each unit is manufactured from high-density aluminum alloy for optimal thermal conductivity and is precision-machined to ensure absolute deck flatness for a superior head gasket seal. Whether you are performing a top-end overhaul on a Chevrolet Malibu, Equinox, or GMC Terrain, this fully loaded 2.4L Ecotec head provides the mechanical integrity required to restore factory horsepower and fuel efficiency.

🛠️ In-House Machining Process

• Debris-Free Preparation: Every new casting is chemically cleaned and blown out to remove all residual machining oils, metal shavings, and manufacturing debris. This ensures your oiling system remains uncontaminated from the first start-up.

• In-House Precision Machining: Unlike “shelf-stock” heads, we perform all final machine work in-house. This includes final guide sizing and precision valve seat cutting to ensure perfect geometry and clearances before the head reaches the assembly bench.

• Pressure & Integrity Testing: To go beyond the factory standard, we pressure-test every head to 60 PSI. This verifies that the casting is free of porosity leaks or internal defects that could compromise the cooling or oiling systems.

• Dimensional Inspection: Our technicians perform a multi-point inspection of the gasket-sealing surface and bore alignment. This ensures the head is perfectly flat and meets tight OEM tolerances for a flawless fit.

• Professional Assembly & Setup: Valvetrain components are installed and verified in a clean-room environment. We check spring heights and seal seating to ensure the assembly is balanced and ready for high-performance use.

• Vacuum-Seal Verification: Every intake and exhaust port is Vacuum Tested. This guarantees a 100% airtight seal between the valves and seats, ensuring maximum compression and peak performance right out of the box.
