Ford Racing 7.3L Left Hand CNC Ported Cylinder Head

When you're looking to get the most out of your 2020 and newer Ford Super Duty with the 7.3L gasoline engine, this CNC ported left-hand cylinder head from Ford Racing is a serious upgrade. This isn't just a stock replacement; it's a performance component designed to improve airflow into your engine, which is key for making more power. It's the same type of head used in the Ford Performance Megazilla™ crate engine, so you know it's built for serious performance.

This cylinder head is cast from aluminum and features CNC-ported intake and exhaust runners. The intake ports are sized at 55mm (2.165 inches) and the exhaust ports at 42.4mm (1.670 inches), with a 62.4cc combustion chamber. It comes fully assembled with PAC 1282LX valve springs and R393 retainers, ready to be installed. The flow data shows impressive numbers, with 390-415 CFM on the intake and 140-150 CFM on the exhaust at 28 inches of water pressure on a 4.250-inch bore, indicating a significant improvement over stock airflow capabilities.

This is the left-hand side cylinder head; the right-hand side is available separately. It's important to note that this part is not CARB approved and cannot be shipped to California. For optimal performance, ensure you have the correct supporting components and follow the manufacturer's installation guidelines.
