Description
Remanufactured Ford Ranger 2.3L 8-Plug “Large Spring” Cylinder Head
Expertly Rebuilt for 1988-1995 Ford & Mazda 2.3L Engines
Restore your engine’s mechanical integrity with this precision-remanufactured Ford 2.3L/2.5L 8-plug cylinder head. Featuring the reinforced ‘Large Spring’ architecture, this casting is engineered for superior valvetrain stability in high-duty cycle and high-mileage applications. Every unit undergoes a multi-stage thermal normalization process and rigorous pressure testing to ensure a zero-defect foundation. To guarantee a high-pressure combustion seal, the deck is PCD-milled on our Rottler S85A to achieve the ultra-low Surface Roughness (Ra) required for modern sealing standards. With multi-angle valve seat geometry and ultrasonic cleaning of all internal oil galleries, this head meets or exceeds OEM specifications for long-term durability and consistent compression.
🛠️ In-House Machining Process
- Cleaning: Fully disassembled and thermally cleaned.
- Soda Blasted: Castings are blasted with Sodium Bicarbonate. Because baking soda is water-soluble, there is zero risk of abrasive media clogging oil passages.
- Pressure Testing: Tested to 60 PSI to ensure no cracks or porosity leaks.
- Surfacing: All heads are resurfaced on our Rottler S85A for a precision gasket-sealing surface.
- Valve Job: Multi-angle valve job performed; every port is Vacuum Tested to ensure valves are seated 100% airtight.
