Product Details
S&S Cycle is well-known for building high-performance engine components for Harley-Davidson motorcycles. This Super Stock® cylinder head kit is designed for 1979 through 1984 Big Twin models, featuring a 3-5/8 inch bore and a dual plug design. This setup is intended to improve combustion efficiency and performance for your engine.
The heads are constructed from aluminum and come with a natural finish. The dual plug configuration allows for a more complete and efficient burn of the air-fuel mixture within the cylinder, which can lead to improved power delivery and throttle response. This kit is a substantial upgrade for riders looking to get more out of their Big Twin engine.
This kit includes the cylinder heads. Please note that these heads are not CARB approved and cannot be shipped to California. It's always a good idea to consult your service manual for specific installation procedures and any other components you might need to complete your engine build.
