The **S-809 9000 Gasket Set** is a popular aftermarket gasket kit designed for older General Motors engines, particularly those in the **LS1, LS6, and related small-block V8 applications** (e.g., 5.0L, 5.3L, 5.7L, 6.0L). Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros of the S-809 9000 Gasket Set**

1. **High-Quality Materials**

- The kit uses **copper-faced gaskets** with **butyl rubber** for improved sealing and durability compared to standard rubber gaskets. This reduces the risk of oil leaks, especially in high-performance or high-temperature applications.

- The **oil pump gasket** is often reinforced with a **copper insert**, which helps prevent oil leaks over time.

2. **Compatibility with Aftermarket Modifications**

- Designed to work well with **performance upgrades** such as turbocharging, supercharging, or forced induction, where gasket integrity is critical to prevent leaks under increased stress.

- Often used in **restomod projects** where stock gaskets may degrade faster due to higher operating temperatures or modified oil flow paths.

3. **Reputation for Reliability**

- The **9000 series** is known for being a step above basic gasket kits, offering better longevity than OEM or budget alternatives. Many builders and mechanics trust this brand for critical engine components.

- Frequently recommended for **high-mileage engines** where stock gaskets may have already worn out.

4. **Easy Installation**

- The gaskets are **pre-cut and pre-drilled** to fit standard GM small-block applications, reducing the risk of installation errors.

- Includes **clearance shims** where needed (e.g., for valve covers or oil pans) to ensure proper fitment without interference.

5. **Widely Available and Supported**

- Sold by reputable suppliers (e.g., **Jegs, RockAuto, Summit Racing**) and often comes with **detailed installation instructions**.

- If issues arise, the manufacturer or seller typically provides **customer support** or replacements if defects are found.

6. **Cost-Effective for Performance Builds**

- While not the cheapest option, it strikes a balance between **quality and price**, making it a practical choice for enthusiasts who want to avoid frequent gasket failures.

### **Cons of the S-809 9000 Gasket Set**

1. **Not Universal (Engine-Specific)**

- The kit is **not a one-size-fits-all solution**. It is tailored for **GM small-block V8 applications**, particularly those with **LS1/LS6 architecture** (e.g., 5.0L, 5.3L, 5.7L, 6.0L). Buyers must verify compatibility with their **specific engine block and application** (e.g., LS1 vs. LS2 vs. Gen III).

- **Non-GM engines** (e.g., Ford, Chevy big-blocks, or non-LS platforms) will require a different kit.

2. **Potential for Overkill on Stock Engines**

- For **stock or lightly modified engines** running at normal temperatures and pressures, a **basic OEM or budget gasket set** (e.g., Fel-Pro or Sealed Power) may suffice. Upgrading to the S-809 may be unnecessary unless the engine is **high-mileage, modified, or subjected to extreme conditions**.

- The **higher cost** of the 9000 series may not justify the upgrade for casual drivers.

3. **Installation Can Be Fussy**

- While pre-cut, **misalignment or improper torque** during installation can still lead to leaks. Requires **careful surface preparation** (sanding gasket surfaces, using gasket maker, and following torque specs).

- **Valvetrain components** (e.g., rocker arms, pushrods) must be removed, which can be time-consuming for DIYers.

4. **Limited Longevity in Extreme Conditions**

- While better than stock, **copper-faced gaskets are not indestructible**. In **extreme high-performance applications** (e.g., 1000 HP turbocharged engines), **steel-reinforced or composite gaskets** (e.g., **Fel-Pro 6000 or 7000 series**) may be more appropriate.

- **Butyl rubber can degrade** over time with **high heat or oil contamination**, so replacement intervals should still be monitored.

5. **Price Point**

- The **S-809 9000 kit is more expensive** than basic gasket sets (e.g., $100 $200 vs. $30 $80 for OEM). This cost may deter budget-conscious buyers unless they prioritize durability.

- **Additional costs** may arise if **gasket maker, torque tools, or surface prep supplies** are needed for a proper job.

6. **Mixed Reviews on Specific Gaskets**

- Some users report **oil pump gasket leaks** or **valve cover leaks** over time, though these are often attributed to **poor installation rather than the gasket itself**.

- **Head gaskets** in the kit are **not as robust as high-performance alternatives** (e.g., **Fel-Pro 6000 or ARP gaskets**) for extreme builds.

### **Conclusion**

The **S-809 9000 Gasket Set** is a **solid mid-range upgrade** for GM small-block V8 engines, particularly those in **restomod, high-mileage, or mildly modified applications**. It offers **superior sealing and longevity** compared to OEM gaskets, making it a **practical choice for enthusiasts who want to avoid leaks and extend gasket life**. However, it is **not the best option for stock engines** or **extreme high-performance builds**, where more specialized gaskets may be required.

The kit s **strength lies in its balance of quality and compatibility** with aftermarket modifications, but buyers must ensure **proper installation** to maximize its benefits. For **casual drivers or stock engines**, a **budget gasket set** may be sufficient. For **serious builders**, it serves as a **reliable stepping stone** before moving to premium gaskets if needed.

### **Recommendation**

- You have a **GM small-block V8 (LS1, LS6, or similar)** with **high mileage, modifications, or signs of gasket wear**.

- You are **building a restomod or performance project** where gasket reliability is critical.

- You want a **cost-effective upgrade** over OEM gaskets without going for the most expensive options.

- You are **comfortable with installation** and willing to invest in **gasket maker and proper tools**.

- Your engine is **stock, lightly used, and runs normally** a **basic OEM or Fel-Pro gasket set** will suffice.

- You are building a **highly modified or extreme performance engine** (e.g., 1000 HP turbocharged), where **steel-reinforced or composite gaskets** (e.g., Fel-Pro 6000, ARP) are recommended.

- You are **on a tight budget** and cannot justify the extra cost without clear performance benefits.

- You are **not confident in installation** poor gasket sealing can lead to leaks regardless of quality.

- **Fel-Pro 6000 Series** Better for high-performance applications but pricier.

- **Sealed Power 1000 Series** A good mid-range alternative with copper inserts.

- **OEM Gaskets** Sufficient for stock engines but may fail sooner under stress.

- **ARP Gaskets** Premium option for extreme builds (e.g., forced induction).

**Final Verdict:** The **S-809 9000 Gasket Set is a well-rounded, reliable choice** for GM small-block builds where gasket integrity matters. It is **not the absolute best for every scenario**, but it is a **smart upgrade for most enthusiasts** who want to avoid leaks without overspending. Always **verify compatibility** with your specific engine and **follow installation best practices** to ensure success.
