Review SCHOENFELD Dirt Late Model Long Tube Headers 604 Crate Motor Small

The **Schoenfeld 181606LVG-CM3 Tube Headers** represent a precision-engineered component designed for high-performance automotive applications, particularly tailored for engines featuring pushrod overhead valve (OHV) configurations. These headers are meticulously crafted from **4130 chromoly steel**, a material renowned for its exceptional strength-to-weight ratio, durability, and resistance to heat and stress, ensuring long-term reliability even under the most demanding driving conditions. The **604 motor** designation indicates that these headers are specifically optimized for Ford s iconic 351 Cleveland V8 engine, a powerhouse celebrated for its smooth operation, torque-rich performance, and classic American muscle appeal. The **LVG-CM3** model incorporates a **low restriction, high-flow design**, featuring **large-diameter primary tubes** that minimize backpressure while maximizing airflow into the combustion chambers, thereby enhancing engine breathing and overall horsepower and torque output. The **mandrel-bent tubes** eliminate sharp bends, reducing turbulence and improving exhaust scavenging, which translates to better cylinder filling and more efficient combustion. Each header is **welded at the seams** with a **full penetration butt weld**, ensuring structural integrity and preventing leaks that could compromise performance. The **dual-plane design** with precise valve timing further refines the engine s breathing characteristics, allowing for a more linear power band and improved throttle response. Whether installed on a classic muscle car, a restored street rod, or a high-performance street machine, these headers deliver a noticeable improvement in mid-range torque and top-end horsepower, all while maintaining a timeless aesthetic that complements the engine bay s mechanical heritage. Schoenfeld s attention to detail from the **polished finish** to the **precision machining** makes these headers not just a performance upgrade, but a statement piece for enthusiasts who demand both power and craftsmanship.

### Pros and Cons of buying a Schoenfeld 181606LGVCM3 Tube Headers for a 604 Motor

1. **Compatibility and Fitment** The Schoenfeld 181606LGVCM3 tube headers are specifically designed for the Ford 604 engine (used in the 6.0L Power Stroke diesel). They are engineered to fit seamlessly with the factory intake manifold, ensuring proper alignment and function without modifications.

2. **Performance Enhancement** These headers are constructed from high-quality stainless steel, which reduces heat retention and improves exhaust flow compared to stock headers. This can lead to better engine breathing, increased horsepower, and improved throttle response, especially in turbocharged applications like the 604.

3. **Durability and Longevity** Stainless steel headers are resistant to corrosion, warping, and high-temperature degradation, making them a long-lasting upgrade. They are also designed to handle the high exhaust gas velocities produced by the 604 s turbocharged system.

4. **Sound and Exhaust Note** The design of these headers contributes to a deeper, more aggressive exhaust tone, which is desirable for enthusiasts who appreciate a louder, more engaging exhaust sound.

5. **Easy Installation** Schoenfeld headers are known for their straightforward installation process. They come with gaskets and mounting hardware, and many users report that they can be installed without major modifications to the intake manifold or exhaust system.

6. **Aftermarket Support** Schoenfeld is a reputable manufacturer with a strong reputation in the performance aftermarket. Their products are widely supported by tuners, mechanics, and other aftermarket parts, making troubleshooting and upgrades easier.

7. **Turbocharger Compatibility** The 604 s turbocharger system benefits from improved exhaust flow, which these headers provide. This can help reduce turbo lag and improve overall power delivery, particularly at higher RPMs.

1. **Cost** High-quality headers like the Schoenfeld 181606LGVCM3 are not cheap. They represent a significant investment, especially when compared to stock headers or lower-end aftermarket alternatives. The price may deter budget-conscious buyers.

2. **Potential Tuning Requirements** While these headers can improve performance, they may require a tune from a professional or a tuner to optimize the engine s operation. Without proper tuning, you might experience issues like excessive smoke, poor fuel economy, or even engine damage due to increased exhaust backpressure or turbo spool issues.

3. **Installation Complexity (for Some)** Although Schoenfeld headers are generally easy to install, some users may encounter challenges if they are not familiar with engine work. For example, removing the intake manifold or exhaust components may require additional tools or experience, especially if the engine has been previously modified.

4. **Weight** Stainless steel headers are heavier than some aluminum alternatives. While this isn t a major concern for most applications, it may be a consideration for those prioritizing weight reduction in their vehicle.

5. **Limited Customization** These headers are designed for a specific application (the 604). If you plan to make further modifications (e.g., swapping turbos, changing camshafts, or altering the intake manifold), you may need additional components to ensure everything works together optimally.

6. **Potential for Exhaust Restriction (if Not Properly Installed)** If the headers are not installed correctly or if there are leaks in the gaskets, it could lead to restricted exhaust flow, negating the performance benefits. Proper sealing and installation are critical.

7. **Resale Value Impact** While high-quality headers can enhance a vehicle s appeal to performance enthusiasts, they may not significantly increase resale value for non-performance buyers. The return on investment in terms of resale may be limited.
