Construction & Design

Manley Race Flo Intake Valves are manufactured with meticulous attention to detail using premium alloys selected for their strength and resistance to heat and wear. The valves feature precision-machined stems and heads to ensure a perfect fit within the cylinder head, promoting optimal sealing and longevity.

The bead loc groove design improves valve retention and reduces the risk of valve failure during high-RPM operation. This design focus maximizes airflow through the intake ports, supporting improved engine breathing and power output while maintaining structural integrity under the intense mechanical and thermal stresses typical of racing environments.

Installation & Fitment

These intake valves are direct replacements for the factory intake valves on 2012–2014 Chrysler 6.4L 392 HEMI engines. Installation follows standard engine assembly procedures and should be performed by a professional or experienced engine builder to ensure proper valve seating and clearance. No modifications to the cylinder head are required, making installation straightforward for race engine builds.
