Manley Performance Race Series Intake Valves

Chrysler HEMI 6.1L Engines

11670-8

Overview:

Manley Performance Race Series intake valves are precision-engineered components designed specifically for Chrysler HEMI 6.1L engines. Crafted to withstand the intense demands of bracket racing, drag racing, and oval track competition, these valves deliver reliable performance for engines operating up to 8000 RPM.

Whether you are a serious racer or a performance enthusiast upgrading your HEMI engine, these intake valves provide the durability and flow characteristics needed to maximize power and efficiency. You’ll benefit from improved valve sealing and enhanced airflow, helping your engine breathe better under high-stress conditions.

Key Features:

These intake valves incorporate advanced design and manufacturing techniques to ensure optimal performance and longevity:

• Specifically designed for Chrysler HEMI 6.1L engines, ensuring perfect fitment and compatibility.
• Race Flo design with a 2.100-inch diameter to maximize intake airflow and improve volumetric efficiency.
• Triple groove valve stems for secure retention and enhanced valve guide stability during high RPM operation.
• Constructed from high-quality materials engineered to withstand the rigors of racing environments.
• Optimized for engines operating up to 8000 RPM, making them ideal for bracket, drag, and oval track racing applications.
• Precision machined for consistent sealing and durability under extreme thermal and mechanical stress.
• Designed to improve throttle response and support increased horsepower and torque compared to stock valves.

Construction & Design:

Manley’s Race Series intake valves are manufactured using premium-grade materials selected for their strength and heat resistance. The triple groove stem design enhances valve retention and reduces the risk of valve float or failure at high engine speeds. The 2.100-inch Race Flo valve head is engineered to optimize airflow into the combustion chamber, contributing to improved engine breathing and performance.

Each valve undergoes meticulous machining and quality control processes to ensure precise dimensions and surface finishes, which are critical for reliable sealing and long service life in demanding racing conditions.

Installation & Fitment:

These intake valves are direct replacements for the factory valves in Chrysler HEMI 6.1L engines. Installation requires standard engine assembly procedures and should be performed by a qualified technician familiar with high-performance engine builds.

• Designed for bolt-in fitment with no modifications to the cylinder head required.
• Compatible with engines running up to 8000 RPM without the need for special tuning related to valve fitment.

What's Included:

• Set of 8 Manley Race Series intake valves with triple groove stems and 2.100-inch Race Flo heads.

Ideal For:

This set of intake valves is ideal for:

• Racers competing in bracket, drag, or oval track events using Chrysler HEMI 6.1L engines.
• Performance enthusiasts seeking durable, high-flow intake valves for high-RPM applications.
• Engine builders focused on maximizing airflow and reliability in naturally aspirated or forced induction HEMI builds.

Manley Performance manufactures high-strength engine internals for serious builds—especially forged pistons, connecting rods, valves, and valvetrain components developed for racing and high-output street applications. If you’re building for boost, high compression, or sustained RPM, Manley is a common choice for parts engineered to take abuse and keep power reliable.
