Review JAGUAR 4.2 Big Valve Head

The Jaguar EACT1639P 4.2 Big Valve Head is a high-performance component designed for diesel engines, specifically those fitted with the Jaguar Land Rover's EGR (Exhaust Gas Recirculation) system. This big valve head is an upgrade from the standard unit, offering enhanced performance and durability.

The Jaguar EACT1639P 4.2 Big Valve Head is engineered with larger valves, which allow for a greater volume of air and fuel to enter the combustion chamber. This results in improved engine performance, with increased power output and torque. The larger valves also reduce the likelihood of the valves becoming fouled or blocked, reducing the need for frequent maintenance.

The EACT1639P 4.2 Big Valve Head is made from high-quality materials, including a durable cast iron construction. This ensures that the head is able to withstand the high temperatures and pressures that are generated within the engine. The head also features precision machining, ensuring that the valve seats are perfectly aligned, reducing the risk of leaks and improving engine efficiency.

The Jaguar EACT1639P 4.2 Big Valve Head is compatible with a range of Jaguar and Land Rover vehicles, including the Discovery 4, Range Rover Sport, and Land Rover Defender. It is easy to install, with a straightforward bolt-on design. However, it is recommended that the installation is carried out by a qualified mechanic to ensure that it is fitted correctly and securely.

In conclusion, the Jaguar EACT1639P 4.2 Big Valve Head is a high-quality upgrade for Jaguar and Land Rover engines. Its larger valves provide improved engine performance, while its durable construction ensures that it is able to withstand the demands of high-performance driving. Whether you're looking to improve the performance of your vehicle or simply want to ensure that your engine is running at its best, the Jaguar EACT1639P 4.2 Big Valve Head is a great choice.

Details:

This head has a tappet guide hold down kit on the exhaust side. Intake valves were resurfaced. This head would fit on earlier engines pre-1969 if the two water ports at rear are plugged with a pipe plug. For sale is a nice rebuilt rare big valve head with no air injection ports.

Free shipping in the USA. There are no valve shims installed, so it would need that completed before use. It comes with tappets matching camshafts. It has new valve seats, guides, and exhaust valves.
