Show original supplier description
The EngineQuest EQ-CH181NDA is a new, driver-side (left) SOHC cylinder head specifically designed for Toyota vehicles equipped with the 3.0L V6 3VZFE engine, covering model years 1988-1995. Constructed from high-grade aluminum, this cylinder head is built for durability and performance. Key features include a thicker deck for enhanced strength, an improved design to resist cracking, and a superior port finish for increased airflow. The internal water flow has been redesigned for greater thermal conductivity, complementing the inclusion of hardened exhaust seats and precisely CNC-machined guides and seats. Each head undergoes a rigorous 25-point quality check, and features a 3-angle valve finish for optimal performance. This assembled cylinder head comes complete with 100% new OE-type valves, seals, and valve springs. (Note: OHC assemblies do not include the cam and lifters). EngineQuest asserts that its cylinder heads outperform competitors through these advanced design and manufacturing processes.
