S&S SuperStock Twin Cam
Description:
Our CNC porting service for S&S SuperStock Twin Cam heads is built to deliver race-inspired performance for larger engine builds, while maintaining street-friendly reliability. Designed for those who demand both speed and power, this package optimizes intake and exhaust flow using advanced 5-axis CNC technology, giving your engine the edge it needs to perform at its peak.
Equipped with stainless steel 2.000" intake valves and 1.605" exhaust valves, this porting service ensures smooth airflow throughout the RPM range, whether you're chasing high speeds on the track or just looking to dominate the streets.
