Upgrade your Harley Davidson with the S&S Cycle 99-05 BT Super Stock 79cc Cylinder Head Kit, designed for engines from 1999 to 2005 with a stock crankcase. These high-performance cylinder heads are optimized for stock displacement engines but excel when paired with larger stroker or big bore setups up to 110". The 79cc combustion chamber slightly increases compression, enhancing the performance of most camshafts and delivering better power output. Machined for S&S® compression releases, these heads feature large 1.940" intake and 1.575" exhaust valves that maintain port velocity for strong low and midrange response while providing ample airflow for engines at or slightly above stock size. The valve springs are engineered for high performance, supporting camshafts with lifts up to .585", ensuring durability and optimal valve operation. Compatible with stock rocker boxes, exhaust, and intake manifolds, these heads integrate seamlessly into your existing setup. The wrinkle black powder coat finish matches stock engine components, offering a sleek, durable appearance that resists corrosion and heat. Whether you're aiming for improved acceleration or enhanced top-end power, these cylinder heads are a reliable choice for performance-minded riders seeking to upgrade their Harley Davidson's engine efficiency and output.
