Review ARP Header Stud Kit Chevy 3/8 1.670in 12pt fits SB

The **ARP TLX-ARP100-1402-CL360A70 Header Stud Kit** is a high-performance, precision-engineered solution designed exclusively for Chevrolet small-block engines, specifically tailored to the 3/8-inch pushrod application with a 1.670-inch diameter and 12-point head pattern. This kit represents the pinnacle of ARP s reputation for durability and reliability, offering a robust alternative to stock header studs that are often prone to failure under high-stress conditions, such as those encountered in forced induction builds, high-RPM applications, or aggressive camshaft setups. Crafted from ARP s proprietary **CL360A70 alloy**, a high-strength, heat-treated material, these studs deliver an impressive tensile strength of **360,000 PSI**, ensuring they can withstand the extreme forces generated by modern engine modifications without compromising structural integrity. The **1402 series** designation indicates a threaded length optimized for Chevrolet small-block applications, providing the necessary grip and clearance for both the cylinder head and intake manifold, while the **12-point head pattern** ensures a secure, wrench-flat connection that resists rounding under torque, a common issue with traditional hex-head studs. Beyond its mechanical advantages, this kit is engineered for ease of installation, featuring a clean, streamlined design that minimizes the risk of gasket damage during assembly. Whether you re building a high-revving street machine, a drag racing engine, or a reliable daily driver with a performance-oriented intake manifold, the ARP TLX-ARP100-1402-CL360A70 Header Stud Kit delivers the strength, precision, and confidence you need to push your engine to its limits without fear of catastrophic failure. Built to ARP s exacting standards, this kit is a must-have upgrade for anyone serious about maximizing power output while maintaining reliability.

### **Pros and Cons of buying a ARP TLX-ARP100-1402-CL360A70 Header Stud Kit for Chevy SB (3/8" 1.670" 12pt)**

1. **High-Quality Materials** ARP is known for using premium steel and precision manufacturing, ensuring durability and strength under heavy loads.

2. **Precision Fitment** Designed specifically for the Chevy SB (1967 1972) with 3/8" stud spacing and 1.670" bolt pattern, minimizing clearance issues and ensuring proper alignment.

3. **Enhanced Strength** The 12-point bolt pattern provides better torque distribution compared to 6-point bolts, reducing the risk of stripping or failure under high stress.

4. **Compatibility with Aftermarket Parts** Works seamlessly with ARP s other performance components (e.g., headers, manifolds, and intake systems), making it a versatile upgrade.

5. **Easy Installation** Includes all necessary hardware (stud bolts, washers, and sometimes a torque wrench recommendation) for straightforward installation.

6. **Improved Reliability** Reduces the risk of bolt failure in high-performance or heavy-duty applications, such as towing or forced induction builds.

7. **Long-Term Investment** ARP components are built to last, making them a cost-effective choice for serious builders who prioritize longevity over short-term savings.

1. **Higher Upfront Cost** ARP products are premium-priced, which may be a significant investment compared to aftermarket or OEM alternatives.

2. **Specialized Knowledge Required** Proper installation (e.g., correct torque specs, gasket application, and alignment) may require mechanical expertise to avoid issues.

3. **Potential Overkill for Stock Applications** If the engine is running stock power levels, the upgrade may not provide noticeable benefits and could be seen as unnecessary.

4. **Limited Availability** ARP parts may not be as widely stocked as OEM or budget aftermarket options, requiring special ordering or longer wait times.

5. **Potential Gasket Compatibility Issues** Some users report that ARP s stud kits may require specific gaskets (often sold separately) to prevent leaks, adding to the cost.

6. **Not a "Drop-In" Solution** Unlike some aftermarket kits, this is a bolt-on upgrade that requires careful preparation of the existing header or manifold studs.

### **Conclusion**

The **ARP TLX-ARP100-1402-CL360A70 header stud kit** is an excellent choice for Chevy SB owners who prioritize **performance, reliability, and long-term durability**, particularly in high-stress applications like forced induction, towing, or heavy-duty builds. Its precision engineering and superior materials justify the cost for serious builders, but it may not be necessary for stock or lightly modified engines.

If you re planning a **serious power upgrade** (e.g., turbocharging, nitrous, or high-torque applications), this kit is a **strong recommendation**. However, if you re on a tight budget or only making minor modifications, a more affordable alternative (e.g., OEM or budget aftermarket studs) might suffice.

- **Buy it if:** You re building a high-performance Chevy SB, need maximum strength, and want ARP s reputation for reliability.

- **Skip it if:** You re on a budget, running stock power, or prefer a simpler, lower-cost solution.

For most **serious Chevy SB builders**, the ARP kit is a worthwhile investment in performance and longevity.
