Manley valves are designed to outflow and outperform all others even in the most severe environments. Manley stainless valves feature gorgeous yet durable chrome stems, swirl polished under heads, fully hardened tips, completely machined combustion faces, closely controlled margin heights, and exact stem to seat concentricity to render a finished product that is unsurpassed.
The exhaust valves have been crafted from a XH-426 stainless exhaust material, and the intake valves have been crafted from NK-842 stainless steel. These valves also feature chrome stems, as well as hard tips, and the design will provide improved flow with the “Pro Flo” underhead.
The valves are finished off with a fully machined, swirl polished finish, and come with a 32mm (Standard) or 33mm head diameter (+1mm).
