The NEW PLATINUM series of Pro1 heads have redesigned ports using Dart's 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.
PRO 1 aluminum cylinder heads for small-block V8’s deliver advanced airflow technology at an unbeatable price! We’ve 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. PRO 1 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° heads.

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.
