S&S Cycle 84-99 BT 91cc .064in Manifold Surface Cylinder Heads - Wrinkle Black

If you're rebuilding the top end of your 1984-1999 Big Twin motorcycle and looking for a solid performance upgrade, these S&S Cycle cylinder heads are a well-built option. They feature a 91cc combustion chamber volume, which is a common size for many performance builds, and a .064 inch manifold surface. This specific manifold surface dimension is important for ensuring a proper seal with your intake manifold, preventing vacuum leaks and maintaining consistent engine performance.

These heads are constructed from durable materials and finished in a wrinkle black powder coat that looks sharp and helps resist corrosion. The S&S Cycle name is well-known in the performance V-twin world for producing reliable components that offer improved performance over stock. When you're putting together a custom build or looking to get more out of your engine, choosing quality heads like these can make a notable difference in how your bike runs.

It's important to note that these cylinder heads are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures, especially when dealing with critical engine components like cylinder heads.
