The NEW Dart Platinum PRO1 180 cc Heads have redesigned ports using Darts exclusive wet-flow technology that conditions the intake charge to produce a more homogenous air/fuel mixture in the cylinders. The result is more efficient combustion and more output. This new head consistently produced gains of 24 peak HP and 20 HP across the operating range.
PRO1 aluminum cylinder heads for small-block V8s deliver advanced airflow technology at an unbeatable price! We have improved the original small-block design with extra-thick decks and high-capacity water jackets that increase reliability in high-performance applications. Hardened exhaust seats and long-lasting mag-bronze valve guides significantly extend cylinder head life. 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. Available with 64cc or 72cc combustion chambers and angle or straight spark plugs. Assemblies are available for hydraulic, hydraulic roller , flat tappet and roller cams. - 180cc intake ports

On all complete assembly packages, it is very possible that the valve springs are not correct for your camshaft. All valve springs should be checked for compatibility to your camshaft. Severe wear of valve train components and severe engine damage could result from failure to do this. Check spring requirements before heads are installed on the engine. If in doubt please contact your camshaft manufacturer or USA Performance Parts. We do carry optional springs for all of your needs.
