The LS engine family has become one of the most popular engine platforms for performance enthusiasts and racers alike. With its small size, light weight, and high power output, the LS engine has become a go-to choice for many applications. A key component of the LS engine is the cylinder head, which plays a major role in the engine’s performance. In this article, we’ll explore the different types of LS cylinder heads available and the benefits they offer.
The most common type of LS cylinder head is the factory LS head. These heads are designed by General Motors and are used on all LS-based engines. The factory LS head is designed for reliable and efficient power production, and is a great choice for stock builds or mild performance upgrades. The factory LS head features an aluminum construction and a single-overhead camshaft design. The head also features large intake and exhaust ports, as well as a “cathedral” port design, which helps to improve airflow and power production.
Aftermarket LS Cylinder Heads
Aftermarket LS cylinder heads are designed to offer improved performance over the factory LS head. These heads are often made from aluminum or other lightweight materials, and feature larger intake and exhaust ports than the factory head. They also feature more aggressive valve angles and larger valves, which help to improve airflow and power production.
Aftermarket LS cylinder heads are available in a variety of configurations, including single-overhead camshaft, dual-overhead camshaft, and even four-valve designs. The heads also feature different port designs, such as “rectangular” or “elliptical” ports, which can help to further improve airflow and power production.
LS Cylinder Head Upgrades
In addition to aftermarket LS cylinder heads, there are also a number of upgrades available for the factory LS head. These upgrades include larger valves, porting, and other modifications designed to improve airflow and power production. Upgrading the factory LS head can be a great way to get more power out of the engine without having to invest in an aftermarket head.
Conclusion
The LS engine is an incredibly popular platform for performance enthusiasts, and the cylinder head plays a major role in the engine’s performance. There are a number of different types of LS cylinder heads available, including factory LS heads, aftermarket LS heads, and upgrades for the factory LS head. Each type of head offers its own benefits, and it’s important to choose the right type for your application. With the right cylinder head, you can get the most out of your LS engine.
