LS engines are known for their powerful performance and reliability, making them a popular choice for performance enthusiasts and race car drivers. If you're looking to take your LS engine to the next level, LS2 heads may be just what you need. But what exactly are LS2 heads, and how can they enhance your engine's performance? In this article, we'll take a closer look at LS2 heads and what they can do for your LS engine.
What Are LS2 Heads?
LS2 heads are a type of cylinder head designed for LS engines. These heads are specifically designed to increase airflow and improve engine performance. LS2 heads are a popular upgrade for LS engines, as they can increase horsepower and torque, improve throttle response, and provide better overall engine performance.
How Do LS2 Heads Work?
LS2 heads work by increasing the airflow to the engine, which in turn improves engine performance. This increased airflow is achieved through several design features, including larger ports, larger valves, and better flow characteristics. LS2 heads are designed to work with LS engines and are typically a direct bolt-on replacement for the stock cylinder heads.
Benefits of LS2 Heads
Some of the benefits of LS2 heads include the following:
- Increased horsepower and torque
- Improved throttle response
- Better overall engine performance
- Increased efficiency and fuel economy
- Direct bolt-on replacement for stock cylinder heads
Choosing LS2 Heads for your Vehicle:
When choosing LS2 heads, it's important to consider your engine's specific needs and performance goals. The primary considerations to remember while choosing LS2 heads are the intake manifold port type, and your block’s piston bore size.
Factory intake ports come in three types — cathedral, square, and raised square. The most commonly-used intake port is the cathedral port. Designed to work on Gen III engines like the LS1, LS6, and LS2, it offers a good torque balance, making it great for street use.
Regarding bore size, the 3.89-inch bore LS1 and LS6 engines can use cylinder heads designed for LS2 engines. If you use heads designed for larger bore sizes, there is a chance that the valves will contact the edges of the cylinder bore, which is a risk you don’t want to take. The LS2 cylinder heads are also acceptable for LS2 and LQ9 engine blocks with a 4.00-inch bore. While the 6.2L engines have a 4.065-inch bore size and accept all of the smaller production-style cylinder heads.
Installing LS2 Heads
Installing LS2 heads can be a complex process that requires careful attention to detail. It's important to have a good understanding of your engine and the LS2 heads you've chosen, as well as the necessary tools and equipment. If you're not comfortable with engine work, it's best to have a professional mechanic or engine builder install your LS2 heads for you.
FAQs
