The **Sherman She695-23-1A (695-23-1A) Upper Header Panel** is a meticulously crafted, high-performance component designed exclusively for the 1967 1968 model year of the iconic **Ford Mustang** and **Mercury Cougar**, particularly those equipped with the legendary **390-cubic-inch Cleveland V8 engine** (commonly found in the **GT, GT Fastback, and Boss 302** variants). This upper header panel, part of the **Sheldon Engineering** line of performance exhaust manifolds, is engineered to maximize airflow efficiency while maintaining structural integrity, making it a sought-after upgrade for enthusiasts aiming to enhance throttle response, horsepower, and overall engine breathing.
Constructed from **high-grade, heat-treated steel**, the **She695-23-1A** features a **dual-plane design** with precision-machined ports that optimize exhaust gas flow, reducing backpressure and allowing the engine to exhale more efficiently. The header s **primary and secondary tubes** are strategically contoured to promote a smoother, more linear exhaust pulse, which helps improve low-end torque and mid-range power critical for the Cleveland V8 s naturally aspirated performance. The **welded construction** ensures durability under high-stress conditions, while the **smooth, polished interior** minimizes turbulence, further enhancing exhaust scavenging.
One of the standout features of this header is its **direct bolt-on compatibility** with the stock **390 Cleveland intake manifold**, eliminating the need for additional modifications or adapters. The **clean, factory-style mounting pattern** ensures a secure, leak-free installation, preserving the original engine bay s aesthetic while delivering measurable performance gains. Whether paired with a **high-performance carburetor** like a **Holley 4150** or a **fuel-injected system**, the **She695-23-1A** provides a seamless transition from intake to exhaust, helping unlock the full potential of the Cleveland s **360 400 horsepower** range.
Beyond its performance benefits, the **She695-23-1A** is a nod to the **restomod and high-performance restoration** communities, offering a balance between authenticity and modern efficiency. Its **black oxide finish** not only resists corrosion but also complements the aggressive, muscle-car aesthetic of the era. For collectors and builders seeking to preserve the **1967 68 Mustang s** legendary reputation while pushing it beyond stock specifications, this upper header panel is an indispensable upgrade combining **Sheldon Engineering s reputation for precision** with the timeless power of the Cleveland V8.
### **Pros and Cons of Buying a Sherman She695-23-1A (1967-68 Upper Header Panel)**

2. **Reliability** The original upper header panel was designed for the specific engine and exhaust system of the 1967-68 models. Using an authentic part reduces the risk of leaks, improper sealing, or performance issues caused by mismatched components.
3. **Aesthetic Value** For classic car enthusiasts, original or high-quality reproduction parts enhance the vehicle s historical accuracy and resale value. A well-maintained original header panel can be a point of pride for collectors.
4. **Compatibility with Stock Systems** Since this part was designed for the original engine and exhaust setup, it will integrate seamlessly with stock components, reducing the need for additional modifications or adapters.
5. **Potential for Increased Performance (if properly maintained)** A clean, well-functioning upper header panel contributes to proper exhaust flow, which can improve engine breathing and overall performance, especially if the vehicle is tuned or modified.
6. **Easier Maintenance and Repairs** Original or OEM-replica parts are easier to work with for mechanics familiar with classic vehicles. This can simplify future repairs and ensure that any labor performed is accurate.

#### **Cons:**1. **Cost** Original or high-quality reproduction parts for classic vehicles can be expensive, especially if sourced from specialty suppliers or restored from salvage yards. The price may be significantly higher than aftermarket alternatives.
2. **Availability and Lead Times** Finding an exact match for a 1967-68 Sherman upper header panel may require searching through collectors, salvage yards, or specialized suppliers. Lead times can be long, especially if the part is rare or in high demand.
