The **Brodix N928 Chevy 350 Small Block Head Kit** represents a premium, high-performance upgrade designed to transform stock or mildly modified Chevrolet 350 cubic inch small-block heads into a more robust, high-flowing assembly capable of handling serious power without sacrificing reliability. Engineered with precision and built to exacting standards, these heads are crafted from **high-quality cast iron** and feature a **fully machined, ported, and polished design** that enhances airflow while maintaining structural integrity under extreme loads. The N928 kit includes **fully remachined combustion chambers** (approximately 92 cubic inches per chamber, hence the "N928" designation), which optimize compression ratios for better efficiency and power output, whether you're running pump gas, ethanol blends, or high-octane racing fuel. The **intake ports** are generously sized and meticulously contoured to minimize turbulence and maximize velocity, ensuring a smooth, unrestricted flow of air-fuel mixture into the cylinder. Similarly, the **exhaust ports** are aggressively ported to efficiently evacuate combustion gases, reducing backpressure and improving scavenging critical factors for extracting peak performance from your 350 engine.
Beyond their aerodynamic refinements, these heads incorporate **modern valve train features** that elevate their performance capabilities. The **valve seats** are precision-ground and hardened to resist wear, even under the stress of high-performance fuels and aggressive camshaft profiles. The **valve guides** are oversized and reinforced to accommodate larger valves (typically 1.90" intake and 1.60" exhaust) without compromising durability, while the **valve springs** are upgraded to handle higher RPMs and valve float resistance, ensuring consistent valve operation across the entire rev range. The **pushrod bores** are also enlarged and polished to reduce friction and wear, allowing for smoother operation with aftermarket rocker arms or pushrods. For those seeking an even more aggressive setup, the N928 kit is compatible with **aftermarket valve springs, retainers, and locks**, as well as **stainless steel valves** for enhanced heat resistance and longevity.
One of the standout features of the Brodix N928 heads is their **compatibility with a wide range of engine builds**, making them a versatile choice for everything from street rods and muscle cars to high-performance drag racing and even limited-track applications. The heads are designed to work seamlessly with **modern fuel injection systems**, including **EFI setups**, while also accommodating **carbureted applications** with proper tuning. The **spark plug boss** is reinforced and precisely machined to ensure a secure, leak-free fit with high-quality spark plugs, and the **oil passage** design is optimized for efficient lubrication of the valve train, reducing the risk of premature wear. Additionally, the heads include **fully gasketed surfaces** that are ready for installation, though users are advised to use a high-quality **copper or soft gasket material** to ensure a proper seal without damaging the machined surfaces.
For those prioritizing **durability and longevity**, the N928 heads are built to withstand the rigors of high horsepower applications, often exceeding **600-700 horsepower** with proper supporting components like a strong block, forged internals, and a high-flow fuel system. The **deck surface** is flat and parallel, ensuring a perfect mating with the block, while the **bolt pattern** remains standard, allowing for easy integration with stock or aftermarket manifolds, including **Edelbrock, Holley, or custom-built headers**. The **exhaust port transitions** are smoothly blended to minimize turbulence and improve flow into the headers, making these heads an excellent choice for both **long-tube headers** and **shorty headers** setups. Whether you're building a **high-revving street machine**, a **top-echelon drag car**, or a **reliable daily driver with serious power**, the Brodix N928 Chevy 350 heads deliver a **proven, high-performance upgrade** that combines **precision engineering, aggressive porting, and robust construction** to help you unlock the full potential of your 350 engine.
### **Pros and Cons of Buying Brodix N928 Chevy 350 Heads**
#### **Pros:**1. **Performance Gains** Brodix N928 heads are designed for high-performance applications, offering improved airflow and combustion efficiency compared to stock heads. They are often used in forced-induction builds (turbo/supercharged) and high-RPM applications, delivering better horsepower and torque.
2. **Durability and Strength** Brodix heads are forged from high-quality materials, including 4340 steel, which provides better heat dissipation and resistance to warping or cracking under extreme conditions. This makes them more reliable than cast-iron heads in high-stress applications.
3. **Compatibility with Forced Induction** These heads are specifically engineered to handle the increased cylinder pressures and temperatures associated with turbocharging or supercharging. Stock heads often fail under these conditions, but Brodix heads are built to withstand them.
4. **Better Valve Flow** The porting and valve design of Brodix heads are optimized for maximum airflow, improving both intake and exhaust flow metrics. This leads to better engine breathing and power output, especially at higher RPMs.
5. **Aftermarket Support** Brodix offers a full line of supporting components, including valves, springs, retainers, and gaskets, ensuring easy integration with other performance parts. They also provide detailed installation guides and technical support.
6. **Long-Term Reliability** Forged heads are less prone to failure from thermal stress or mechanical fatigue, making them a more durable choice for aggressive builds compared to stock or even some aftermarket cast heads.
7. **Customization Options** Brodix allows for custom porting and valve sizes, meaning you can tailor the heads to your specific engine setup for optimal performance.

#### **Cons:**1. **Higher Upfront Cost** Brodix N928 heads are significantly more expensive than stock or even some aftermarket cast heads. The premium price reflects their forged construction and performance-focused design, which may not be justified for mild street builds.
2. **Weight** Forged heads are heavier than cast-iron heads, which can slightly increase rotating mass and reduce high-RPM responsiveness. However, this is usually negligible compared to the performance benefits.
3. **Installation Complexity** Swapping to Brodix heads requires careful preparation, including machining the block for proper head gasket surfaces, valve spring retainer clearance, and possibly rocker arm adjustments. This may involve additional labor costs if not done in-house.
4. **Limited Stock Availability** Brodix heads are not as widely stocked as some other brands, so ordering may require patience or special ordering through a performance parts dealer.
5. **Not Ideal for Mild Builds** If you re running a naturally aspirated engine with minimal modifications, the performance gains from Brodix heads may not be worth the cost. Stock or mildly ported heads might suffice for a street or light-duty application.
6. **Potential for Overkill** For some applications (e.g., a stock or mildly modified engine), the power gains from Brodix heads may not be significant enough to justify the expense, especially if other components (like the camshaft or fuel system) are limiting performance.
7. **Maintenance Considerations** Forged heads require proper lubrication and care to prevent issues like valve seat wear or retainer binding. Neglecting maintenance could lead to premature failure, though this is true of any high-performance component.
