Introduction
Welcome to our guide on the best heads for a 6.0 LS engine. If you're looking to upgrade your LS engine's performance, one of the most effective ways to do so is by replacing the stock cylinder heads with aftermarket options. In this article, we will explore some of the top choices for LS heads and discuss their features, benefits, and performance capabilities.
1. Why Upgrade the Cylinder Heads?
Before we dive into the best heads for a 6.0 LS, let's first understand why upgrading the cylinder heads is crucial. The cylinder heads play a vital role in the combustion process, controlling the intake and exhaust flow, as well as housing the valves and spark plugs. Upgrading to aftermarket heads can improve airflow, increase power, and enhance overall engine performance.
2. Considerations for Choosing LS Heads
When selecting the best heads for your 6.0 LS engine, there are several factors to consider. These include:
- Intended use (street, strip, or track)
- Compression ratio
- Desired power gains
- Budget
3. The Importance of Flow
One of the key considerations when choosing LS heads is airflow. Increased airflow allows the engine to breathe better, resulting in improved power and performance. Look for heads with optimized intake and exhaust ports, as well as larger valves, to maximize airflow.
4. LS3/L92 Heads
The LS3/L92 heads are a popular choice for 6.0 LS engines. These heads feature rectangular intake ports and larger valves, allowing for improved airflow. They also have a higher compression ratio, which can further enhance power and torque. LS3/L92 heads are compatible with both stock and aftermarket intake manifolds.
5. Trick Flow GenX 255 Cylinder Heads
The Trick Flow GenX 255 cylinder heads are another excellent option for a 6.0 LS engine. These heads feature a CNC-ported intake and exhaust runners, as well as larger valves. They also have a higher compression ratio, resulting in increased power. The Trick Flow GenX 255 heads are designed for high-performance applications and can provide significant power gains.
6. AFR LSX Mongoose 12° Cylinder Heads
The AFR LSX Mongoose 12° cylinder heads are specifically designed for high-horsepower LS engines. These heads feature CNC-ported intake and exhaust runners, as well as larger valves. They also have a 12-degree valve angle, which helps improve airflow and combustion efficiency. The AFR LSX Mongoose 12° heads are ideal for racing applications where maximum power is desired.
7. Edelbrock E-Street Cylinder Heads
If you're looking for a budget-friendly option, the Edelbrock E-Street cylinder heads are worth considering. These heads offer improved airflow and performance over stock heads, without breaking the bank. They feature optimized intake and exhaust ports, as well as larger valves. The Edelbrock E-Street heads are a great choice for street-driven 6.0 LS engines.
8. Dart Pro 1 LS3 CNC Cylinder Heads
The Dart Pro 1 LS3 CNC cylinder heads are designed for high-performance LS engines. These heads feature CNC-ported intake and exhaust runners for maximum airflow. They also have larger valves and a higher compression ratio, resulting in improved power and torque. The Dart Pro 1 LS3 CNC heads are a popular choice for both street and strip applications.
9. Benefits of Aftermarket LS Heads
Upgrading to aftermarket LS heads offers several benefits, including:
- Increased power and torque
- Improved airflow and combustion efficiency
- Enhanced engine durability
- Compatibility with aftermarket camshafts and other performance upgrades
10. Installation Considerations
When installing aftermarket heads on your 6.0 LS engine, there are a few things to keep in mind:
- Proper head gasket selection
- Valve train compatibility
- Professional installation or experienced DIY skills
- Tuning and calibration adjustments
11. Dyno Testing and Tuning
After installing aftermarket heads, it's essential to perform dyno testing and tuning to optimize performance. This involves adjusting fuel and ignition settings to ensure the engine runs at its best. A professional tuner can help you extract the maximum potential from your upgraded LS heads.
12. Considerations for Forced Induction
If you're planning to add forced induction (such as a supercharger or turbocharger) to your 6.0 LS engine, it's crucial to choose heads that are compatible with forced induction applications. These heads typically have reinforced casting and thicker valve seats to withstand the increased stress and heat generated by forced induction.
13. LS Head Comparison Chart
To help you compare the different LS head options, here's a handy chart highlighting their key features:
| Head | Intake/Exhaust Runner Size | Valve Size | Compression Ratio | Application |
|---|---|---|---|---|
| LS3/L92 | Rectangular | Larger | Higher | Street/Strip |
