Cylinder head selection is one of the most important contributors to an engine’s performance, because it ultimately determines how much air the engine can process to generate horsepower.
The heads for regular-production LS-family engines are renowned for exceptional airflow attributes and offer significant power-building capability with traditional machining that enhances the volume of the intake ports and/or reduces restriction within the ports.
