Features & Product Details

Okay you’re in the middle of a motor rebuild and so far you have all your ducks in a row. You’ve got big turbo, forged pistons, flat bill hat, energy drink, oh yeah, VALVES! The Manley Race Series Valves, and Extreme Duty Valves have been designed to make sure your head is moving air effectively so that your engine is using power to its fullest potential.

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 head diameter.
