Review EDELBROCK 671 871 Small Block Chevy Victor Jr Cylinder Heads Crane Gold Rockers Arp

The **Edelbrock 671/871 Block Chevy Victor Cylinder Heads with Crane Rockers and ARP Fasteners** represent a premium, high-performance upgrade package designed to transform stock or mildly modified small-block Chevy engines into a high-revving, high-flowing powerhouse capable of handling aggressive camshafts, forced induction, or extreme naturally aspirated applications. These heads are meticulously crafted from **9310 aluminum**, a material renowned for its exceptional heat dissipation and strength, ensuring reliability under the most demanding conditions. The **Victor-style combustion chamber design** (671cc per chamber) strikes an ideal balance between high-lift performance and volumetric efficiency, making them an excellent choice for both street and track applications, whether paired with a mild 288-degree cam or a more aggressive 300 degree grind. The **Crane rocker arms** included in this package are precision-machined from aircraft-grade aluminum, featuring **1.6:1 mechanical advantage** for optimal valve lift and a smooth, consistent operation that minimizes valve train wear while maximizing airflow. These rockers are paired with **ARP (Advanced Race Products) fasteners**, including **ARP head studs, rocker studs, and main cap bolts**, which are engineered to withstand extreme clamping forces and high cylinder pressures, ensuring structural integrity even under the most punishing conditions. The **1.625-inch valve stems** and **1.940-inch intake valves** (with 1.50-inch exhaust valves) provide ample flow area, while the **integrated valve springs** (with optional solid lifters for high-lift applications) deliver consistent valve closure and prevent valve float at high RPM. Whether you're building a **high-revving stroker engine**, a **nitrous-ready monster**, or a **forced induction beast**, these heads offer a robust foundation for serious horsepower gains. The **Edelbrock 671/871 package** is a complete solution, combining proven porting, durable hardware, and a reputation for reliability, making it a top-tier choice for Chevy enthusiasts who demand nothing less than peak performance.

### **Pros and Cons of Buying Edelbrock 671/871 Block Chevy Victor Cylinder Heads with Crane Rockers and ARP Studs**

#### **Pros**

1. **Performance Gains** The Edelbrock Victor heads are designed for high-performance applications, offering improved airflow compared to stock heads. The larger combustion chambers and optimized porting enhance breathing, which translates to better horsepower and torque, especially when paired with a forced induction system or a high-performance camshaft.

2. **Durability and Strength** The 671/871 block heads are forged from high-quality steel, making them significantly stronger than cast-iron heads. This reduces the risk of warping, cracking, or failure under high stress, which is critical for aggressive builds, turbocharging, or nitrous applications.

3. **Compatibility with Aftermarket Parts** These heads are widely used in the performance community, meaning there is a vast selection of supporting parts, including intake manifolds (e.g., Edelbrock Victor or Performer RPM), exhaust manifolds, and valve springs. They also work well with aftermarket cams, lifters, and pushrods.

4. **Crane Rockers Advantage** The inclusion of Crane rockers (typically the 1000 series or similar) improves valve train efficiency by reducing friction and allowing for better valve lift and duration. This can further enhance performance, especially with aggressive cam profiles.

5. **ARP Studs for Head Gasket Integrity** ARP (Advanced Racing Products) studs are a premium choice for securing cylinder heads. They provide superior clamping force and prevent stud stretch, which is crucial for maintaining a proper head gasket seal under high boost or high RPM conditions. This reduces the risk of leaks and ensures consistent compression.

6. **Versatility** These heads can be used in a variety of Chevy applications, including small-block (265 396 ci) and some big-block configurations, depending on the specific model. They are also compatible with both naturally aspirated and forced induction builds.

7. **Warranty and Support** Edelbrock offers a solid warranty on their heads, and Crane/ARP provide reliable support for their components. This gives buyers confidence in the longevity and performance of the parts.

8. **Aesthetic Appeal** For those who care about appearance, these heads have a clean, polished look that complements high-performance builds, especially when paired with matching intake and exhaust components.

#### **Cons**

1. **Cost** Edelbrock Victor heads, Crane rockers, and ARP studs are not cheap. The total investment can be substantial, especially when factoring in installation labor, gaskets, and other necessary components. This may be a barrier for budget-conscious builders.

2. **Installation Complexity** Swapping to these heads requires careful preparation, including machining the block (if necessary), proper gasket surface prep, and precise torque specifications. Improper installation can lead to leaks, warping, or even catastrophic failure. This often necessitates professional installation, adding to the cost.

3. **Weight** Forged steel heads are heavier than cast-iron heads. While this adds strength, it can also increase the rotating mass of the engine, potentially affecting drivability and throttle response, particularly in high-revving applications.

4. **Limited Stock Compatibility** These heads are not drop-in replacements for stock applications. They require modifications to the block (e.g., decking, port matching) and may not fit stock manifolds or intake systems without additional work. This can complicate retrofits.

5. **Maintenance Considerations** Forged heads and Crane rockers require proper lubrication and maintenance to prevent wear or failure. Neglecting oil changes or using low-quality oil can lead to premature valve train issues.

6. **Potential for Overkill** If the engine is not heavily modified or not intended for extreme power levels (e.g., 1,000 hp), the benefits of these heads may not be fully realized. For mild street builds, a cast-iron head upgrade (e.g., Edelbrock Performer RPM) might be sufficient and more cost-effective.

7. **Learning Curve** Building an engine with these components involves learning new techniques, such as proper head stud torque patterns, valve spring installation, and valve train setup. Beginners may find the process overwhelming without guidance.

### **Conclusion**

The Edelbrock 671/871 Block Chevy Victor cylinder heads paired with Crane rockers and ARP studs are one of the best high-performance upgrades for a Chevy small-block or compatible big-block engine. They offer significant gains in power, durability, and reliability, making them ideal for serious builders targeting forced induction, nitrous, or high-RPM applications. However, the cost, installation complexity, and weight considerations mean they are best suited for enthusiasts with a dedicated performance project or those willing to invest in a high-quality build.

For those on a tighter budget or building a mild street engine, a cast-iron head upgrade (e.g., Edelbrock Performer RPM or JE heads) may provide adequate performance without the premium price tag. But if your goal is maximum power, longevity, and a future-proof engine, the Victor heads with Crane rockers and ARP studs are an excellent choice.

### **Recommendation**

- You are building a high-performance engine for forced induction, nitrous, or aggressive camshafts.

- You have the budget to invest in a premium upgrade and are willing to put in the work for proper installation.

- You prioritize durability, strength, and long-term reliability over cost savings.

- You plan to use supporting aftermarket parts (e.g., intake, exhaust, valve springs) that complement these heads.

- You are on a tight budget and can achieve similar gains with a more affordable cast-iron head upgrade.

- Your engine is a mild street build with no plans for forced induction or extreme power levels.

- You lack experience with engine assembly and are not prepared for the complexity of installation.

- You prioritize weight reduction or simplicity over maximum performance.

For most serious Chevy builders aiming for serious power, the Edelbrock Victor heads with Crane rockers and ARP studs are a worthwhile investment. Just ensure you have the proper tools, knowledge, and supporting components to make the most of them.
