This guide will walk you through everything you need to know about purchasing a Harley cylinder head rebuild kit, ensuring you get the best value for your money and keep your Harley Davidson engine running smoothly.
What's Included in a Harley Cylinder Head Rebuild Kit?
A typical Harley cylinder head rebuild kit contains a variety of parts designed to restore your cylinder heads to like-new condition. These commonly include:
- Valve Guides: These guide the valves as they open and close, preventing wear and tear.
- Valve Seals: Prevent oil from leaking into the combustion chamber.
- Valve Springs: Essential for returning the valves to their closed position.
- Valve Spring Retainers: Secure the valve springs in place.
- Valve Stem Seals: Prevent oil leakage past the valve stems.
- Gaskets: Various gaskets are necessary to seal the cylinder head to the engine block.
- Other Hardware: Bolts, washers, and other small parts required for assembly.
The specific components included will vary depending on the kit and the year and model of your Harley. Some kits might be more comprehensive than others, offering additional components like valve lapping compound or new valve keepers. Always carefully review the kit's contents list before purchasing to ensure it's suitable for your needs.
What are the Different Types of Harley Cylinder Head Rebuild Kits?
Harley cylinder head rebuild kits can be categorized based on several factors:
- By Engine Type: Kits are specific to the engine type (e.g., Evolution, Twin Cam, Milwaukee-Eight). Using the wrong kit can lead to serious engine damage.
- By Year & Model: Even within the same engine type, there can be variations between different years and models of Harleys. Always double-check compatibility before buying.
- By Component Inclusivity: Some kits are "basic" offering only essential parts, while others are "premium" including more components and potentially higher-quality parts.
Choosing the right kit depends on the condition of your cylinder heads and your budget. If your cylinder heads are severely worn, a more comprehensive kit might be necessary.
Where Can I Buy Harley Cylinder Head Rebuild Kits?
You can find Harley cylinder head rebuild kits from various sources:
- Online Retailers: Sites like eBay, Amazon, and specialized motorcycle parts websites offer a wide selection of kits. Be sure to check seller reviews before purchasing.
- Motorcycle Parts Dealers: Local motorcycle parts dealers often carry a selection of Harley parts, including rebuild kits. The advantage here is the ability to speak with a knowledgeable expert who can guide your purchase.
- Harley-Davidson Dealerships: Dealerships are a reliable source, but they may be more expensive than other options. However, they offer genuine Harley parts.
How Do I Choose the Right Harley Cylinder Head Rebuild Kit?
Selecting the correct kit involves several crucial steps:
- Identify your engine type and year: This is the most critical step to ensure compatibility.
- Assess the condition of your cylinder heads: A thorough inspection will help determine the extent of the rebuild required.
- Read reviews: See what other customers have to say about the kit's quality and ease of installation.
- Compare prices: Look for the best value without compromising on quality.
Remember that using a substandard kit can lead to further engine damage, so it's always best to invest in a reputable brand and high-quality parts.
What Tools Do I Need to Rebuild Harley Cylinder Heads?
Rebuilding Harley cylinder heads is a complex process requiring specialized tools. You will typically need:
- Valve Spring Compressor: Essential for safely compressing valve springs.
- Torque Wrench: Ensures proper tightening of bolts to prevent damage.
- Various Wrenches and Sockets: Different sizes are needed for various bolts and nuts.
- Valve Lapping Tool (Optional): Used for lapping valves to ensure a proper seal.

Are there any alternatives to buying a complete Harley Cylinder Head Rebuild Kit?
You can purchase individual parts instead of a complete kit if you only need to replace specific components. However, this requires a more thorough understanding of your cylinder head's condition and may be more expensive in the long run. This option is usually only advisable for experienced mechanics.
By carefully considering these factors, you can confidently purchase a Harley cylinder head rebuild kit and get your bike back on the road. Remember to always prioritize quality and compatibility for optimal performance and longevity.
