5.7L Hemi V8 Remanufactured Cylinder Head

To address well-known factory reliability issues involving dropped valve seats, each head undergoes a process where new valve seats are installed with higher pressure and peened for enhanced retention. Every unit is subjected to complete disassembly and thorough cleaning in a hot tank before being pressure tested to ensure casting integrity. All valve guides are replaced as necessary, and new valve stem seals are installed to ensure optimal performance. The heads receive a precision valve job tested for perfect compression and are PCD milled to provide a smooth, consistent finish that meets AERA specifications. Please note that this specific casting does NOT have the EGR hole. Because variations in casting and cooling passages exist across different production years, it is critical to verify a physical match with your existing component before purchase. The heads are remanufactured and may exhibit minor cosmetic imperfections that do not affect functionality. Professional inspection and verification of fitment for your specific vehicle year and trim are recommended.
