1. Affordability: The Job P79 head is often more affordable than a factory-original 280Z head, making it a budget-friendly option for car enthusiasts.

2. Performance: The Job P79 head is known for its improved performance, offering increased power and torque compared to the original head. This is due to its larger intake and exhaust valves, as well as more aggressive camshaft profiles.

3. Durability: The Job P79 head is designed to be more durable than the original head, with improved heat dissipation and strengthened components. This can help reduce the risk of engine failure and increase the lifespan of the engine.

1. Compatibility issues: The Job P79 head may not be compatible with all 280Z engines or engine components. It is important to ensure that the head is compatible with your specific engine before making a purchase.

2. Quality concerns: Some Job P79 heads may have poor quality control, leading to issues such as warping, leaking, or other mechanical problems. It is important to purchase the head from a reputable supplier to minimize the risk of quality issues.

3. Installation challenges: Installing the Job P79 head can be a complex and time-consuming process, requiring specialized tools and expertise. It is recommended to have the head installed by a professional mechanic to ensure proper installation and avoid damage to other engine components.

While the Job P79 head offers improved performance and durability compared to the original 280Z head, it is important to consider the potential compatibility issues, quality concerns, and installation challenges before making a purchase. If you are willing to invest the time and resources into ensuring a proper fit and installation, the Job P79 head can be a cost-effective way to improve the performance of your 280Z engine. However, if you are not comfortable with the potential challenges, it may be worth considering other options, such as a factory-original head or a high-performance aftermarket head.

If you are interested in purchasing a Job P79 head for your Datsun 81-83 280Z, it is recommended to research reputable suppliers and read reviews from other customers to ensure you are purchasing a high-quality product. It is also important to have the head installed by a professional mechanic to ensure proper fit and function. Additionally, consider investing in a performance tune-up and other modifications to fully realize the full potential of the Job P79 head.

Details:

I had the cam reground to a stage 2 grind. The mod procedure is at dot p79 I have e31, e88, and n47 heads also for sale that have not been listed yet. I was going to shave this head and install cam tower shims and shim up the springs and install different valves. If you want to purchase the cam and new rocker arms and lash pads, message me.

Because of this you would not want to use old rocker arms. I was going to modify this head and use it on my 240z project, I decided to use an e31 head. I build them to order, from new valve job to highly modified for increased hp. It is also recommended you check each rocker arm for proper swipe pattern with cam.

This does not include cam, rocker arms, or lash pads. You want to use the 1 rocker arm and lash pad on the 1 lobe of cam, and do this for all 12 cam lobes. P79 head with new valve job. It is recommended that you should use new rocker arms and lash pads.
