Tutorial video Start To Finish Ford 557 W/ kasse SR-71 Heads

The SR-71 heads for a Ford 557 are high-performance aluminum cylinder heads designed specifically for maximizing the output of big-block Ford engines, particularly those based on the 429/460 platform. Developed with precision engineering, these heads are named after the iconic SR-71 Blackbird, reflecting their speed and performance capabilities.
Key Features:
1. Port and Chamber Design:
• CNC-machined intake and exhaust ports for maximum airflow.
• Large combustion chambers (typically around 72-90cc, depending on the model) optimized for high compression ratios.
2. Valves and Flow:
• Designed to accommodate larger valves, often 2.30-inch intake and 1.88-inch exhaust.
• Exceptional flow rates capable of supporting over 900+ horsepower naturally aspirated.
3. Durability:
• Made from high-grade aluminum for weight reduction and improved heat dissipation.
• Reinforced structure to handle high-performance applications, including forced induction and nitrous setups.
4. Compatibility:
• Bolt-on fit for 429/460 engines, but particularly effective on stroked applications like the Ford 557.
• Works seamlessly with matching SR-71 intake manifolds and custom exhaust systems for drag racing or high-output street builds.
5. Performance Gains:
• Designed to significantly increase horsepower and torque by optimizing air and fuel delivery.
• Ideal for applications demanding peak performance, such as drag racing and pro street builds.
These heads are a perfect choice for enthusiasts aiming to push their Ford 557 to its limits
