How tall are tall valve covers?
Tall valve covers are a popular modification for many car enthusiasts, as they can enhance the engine's appearance and provide additional clearance for high-performance components. The height of tall valve covers can vary depending on the specific design and application, but they are generally taller than the stock valve covers that come installed on most production vehicles.
What Are Tall Valve Covers?
Valve covers are the protective housings that sit atop the engine's cylinder heads, covering the valve train components such as the rocker arms, pushrods, and valve springs. Tall valve covers are designed to be taller than the stock valve covers, typically ranging from 1 to 3 inches in additional height. This extra height can provide several benefits, including:
- Increased Clearance: Taller valve covers can accommodate larger or modified valve train components, such as high-lift camshafts, larger valves, or aftermarket rocker arms.
- Improved Aesthetics: Tall valve covers can enhance the engine's appearance, giving it a more aggressive or custom look.
- Better Ventilation: The additional height can improve airflow and heat dissipation around the valve train, which can be beneficial for high-performance engines.
Tall valve covers are commonly used in various automotive applications, from muscle cars and hot rods to high-performance street and race cars.
Typical Heights of Tall Valve Covers
The height of tall valve covers can vary depending on the specific design and application, but they are generally taller than the stock valve covers that come installed on most production vehicles. Here are some typical heights for tall valve covers:
- 1 to 2 inches taller: These are considered "moderately" tall valve covers and are a common choice for many enthusiasts looking to upgrade the appearance and clearance of their engine.
- 2 to 3 inches taller: These "significantly" tall valve covers are often used in high-performance applications where additional clearance is required for larger or modified valve train components.
- 3 inches or more taller: Valve covers in this height range are considered "extremely" tall and are typically reserved for specialized, high-performance engines that require maximum clearance for extensive modifications.
It's important to note that the specific height of tall valve covers can vary depending on the make, model, and engine configuration of the vehicle, as well as the individual preferences and requirements of the car owner or builder.
Choosing the Right Tall Valve Covers
When selecting tall valve covers for your vehicle, it's essential to consider factors such as engine size, valve train modifications, and available clearance in the engine bay. Consulting with a knowledgeable automotive specialist or referring to manufacturer recommendations can help ensure you choose the appropriate tall valve covers that will fit your specific application and provide the desired benefits.
How bad is a valve cover leak?
With a bad gasket, the oil is able to leak into the spark plug wells and eventually soak the spark plugs. This can result in your engine misfiring, which is the failure of a cylinder to ignite during the engine's cycle. Misfires will result in reduced performance, and the spark plugs will need to be replaced.

Do valve covers affect performance?
Engine misfires: A valve cover gasket leak can allow oil to enter the spark plug wells, which can cause misfires and a rough-running engine. Reduced engine performance: If the leak is severe, the engine may lose some performance due to the loss of oil pressure.
What is the best coating for valve covers?
While most powder coatings out perform high-temperature paints, a Cerakote finish performs especially well at high-temperatures, making it ideal for valve covers. Cerakote and other ceramic coatings are often referred to as “exhaust coating” or “high heat coating” in the auto industry.
