Fits 1981–1984 Toyota 2.4L SOHC 22R (Tall Deck) (Non-Turbo)
The Red Line Torquer Series cylinder head is engineered for builders looking to increase low and mid-range torque without sacrificing reliability. Whether you're building a 4x4, towing vehicle, trail truck, daily driver, or mild street performance engine, the Torquer Series provides improved airflow, increased valve control, and the durability needed for years of dependable service.
Unlike other aftermarket cylinder heads, this is a completely new casting manufactured by Toyota's original OEM cylinder head manufacturer using the original Toyota casting molds. Many aftermarket cylinder heads are reverse engineered from worn factory castings, but Red Line Engine Builders offers a cylinder head produced from the original tooling to deliver OEM-quality fit, superior casting integrity, and exceptional reliability.
Each Torquer Series cylinder head receives a precision torque port and bowl blend, improving airflow while maintaining excellent air velocity. The result is increased cylinder filling, stronger throttle response, improved pulling power, and greater torque throughout the usable RPM range.
Pair this cylinder head with your choice of Red Line performance camshaft and roller rocker arm conversion (Add to Cart). The Torquer Series is compatible with Red Line roller camshaft conversions up to the 274 Roller Camshaft, making it the perfect foundation for a powerful and dependable street or off-road engine.
Premium Valvetrain Components
Every Torquer Series cylinder head is assembled using premium nitrided intake and exhaust valves for outstanding wear resistance, durability, and long service life.
Each valve is precision ground and hand lapped during assembly to maximize valve-to-seat contact, providing excellent sealing, improved compression, and efficient heat transfer.
The Torquer Series utilizes high-quality OEM-style cast iron valve guides for excellent longevity while maintaining factory reliability.
Valve control is significantly improved with 135 lb dual valve springs, providing the stability required for more aggressive camshaft profiles while maintaining excellent street manners and long-term durability. These springs are designed to support the complete line of Red Line camshafts up to the 274 Roller Camshaft Conversion.
Premium Valve Seat Materials
The valve seat's primary job is to transfer heat from the valve into the cylinder head, helping prevent burned valves, valve seat recession, and premature wear.
To maximize durability and cooling efficiency, Red Line Engine Builders uses premium valve seat materials specifically chosen for the intake and exhaust operating environments.
Intake valve seats are manufactured from a high-strength iron and chromium alloy treated with magnesium, allowing them to work harden during service while providing excellent heat transfer and wear resistance.
Exhaust valve seats are manufactured from premium 410 stainless steel, providing exceptional resistance to high exhaust temperatures while maintaining outstanding sealing characteristics throughout the life of the engine.
Together these premium materials provide excellent heat dissipation, long-lasting valve sealing, improved compression retention, and exceptional reliability for towing, off-road use, daily driving, and mild performance applications.
Precision Torque Porting
Each Torquer Series cylinder head receives a precision torque port and bowl blend designed to increase airflow while maintaining high intake port velocity.
Rather than maximizing port volume, the Torquer Series focuses on improving cylinder filling where most street and off-road engines spend their time operating. The result is quicker throttle response, increased low-end torque, stronger mid-range power, and improved overall drivability without sacrificing reliability.
This cylinder head is an excellent match for trucks running larger tires, towing applications, trail vehicles, and street performance engines that demand broad, usable power.
