Description

The S&S Cycle 89cc Super Stock® Cylinder Heads are fully assembled with high-performance valve springs and valves, ready for installation on '99-'05 engines with stock crankcases. These heads are particularly effective for motors over 103" or those utilizing high-compression pop-up pistons. The combustion chamber is designed to provide a slightly higher than stock compression ratio, optimized for larger displacement engines. Featuring large 2.000" intake and 1.605" exhaust valves, these heads maintain excellent port velocity for strong low- and mid-range response while ensuring ample airflow for enhanced performance at higher RPMs. The intake ports flow 264 CFM (Cubic Feet per Minute), a significant upgrade from the stock head's 182 CFM. These cylinder heads are compatible with stock rocker boxes, exhaust systems, and intake manifolds for straightforward installation. Upgrade your motorcycle's performance with these high-quality, made-in-the-USA cylinder heads. They are powder-coated silver for great looks and durability.
