Product details
The mildest of the ported GTV-2 sets, using 40mm intake and 35.5mm exhaust valves, with a CNC wedge-port finish. That valve size is the same as the standard GTV-2 head, so the heads suit an engine that wants better flow without a large-valve combination. The set is assembled with stainless valves, racing seats, bronze guides, and 4037 dual springs.
