S&S Cycle 84-99 Performance Replacement Low Compression 76cc Cylinder Heads - Wrinkle Black

What you get with this S&S Cycle kit are a pair of performance replacement cylinder heads, specifically designed for 1984 through 1999 Harley-Davidson Big Twin engines. These heads feature a 76cc combustion chamber volume, which is considered low compression for these engines, making them a solid choice if you're looking to build a reliable powerplant that runs cooler or if you plan on using a camshaft that produces more dynamic compression. The wrinkle black powder coat finish not only looks sharp but also offers a durable surface that resists corrosion and wear.

S&S Cycle has a long history of building performance parts for Harley-Davidson motorcycles, and these heads are a testament to that experience. The 76cc chamber size is a key specification that influences how the engine breathes and performs. Lower compression heads like these can be beneficial for several reasons. They can help prevent detonation or knocking, especially in warmer climates or when paired with certain camshafts that might otherwise push static compression too high. This also means they can be a good option if you're not planning on a full engine rebuild and want to retain some of the stock engine's characteristics while still gaining performance and reliability.

When installing these heads, it's important to ensure you have the correct gaskets and hardware, as these are typically sold separately. The wrinkle black finish is applied using a powder coating process, which creates a tough, uniform layer. This finish is designed to hold up to the heat and vibration inherent in a V-twin engine, maintaining its appearance over time. If you're working on a classic Big Twin from the 84-99 era and want to improve its breathing and overall performance with a well-built component, these S&S Cycle heads are a popular option.
