Product details
This assembled GTV-2 head pairs 90.5/92mm cylinders with single high-rev valve springs. The Manley stainless valves measure 40mm intake and 35.5mm exhaust, with chromoly retainers and hardened keepers. It is the single-spring version of this head, so the spring setup can be chosen to suit the engine's valve train.
