NOW with MANLEY Race-Flow Valves
Above Added: Tue May 8, 2012, 3:48 pm EST
The NEW DART PLATINUM Pro1 Heads have redesigned ports using Darts exclusive wet-flow technology that results in more efficient combustion and more output. This new head consistently produced gains of 24 peak HP and 20 HP across the operating range.
We have improved the original small-block design with extra-thick decks and high-capacity water jackets that increase reliability in high-performance applications. PRO1 heads are engineered for easy installation. They use standard small-block pistons, headers, and valvetrain components, and are bolt-on replacements for most conventional 23 degree heads.
