Product details
This GTV-2 version uses dual high-rev valve springs for 90.5/92mm cylinders. It is assembled with 40mm intake and 35.5mm exhaust Manley stainless valves, chromoly retainers, and three-angle valve work. Match the dual-spring setup to the full valve train rather than treating it as an automatic substitute for a single-spring head.
