What parts are included with this cylinder head kit?

This kit includes the cast aluminum cylinder head, cam caps, and bolts. It is designed for an out-of-the-box installation. However, valves, springs, retainers, and lifters are sold separately and will need to be purchased to complete the assembly.

What kind of performance improvements can I expect?

The unshrouded combustion chamber and blended bowl are designed to improve airflow. The competition-grade valve job and shortened valve guides for high-lift cams aim to provide greater torque and enhanced power. The stock-shaped ports are tuned for high performance.

What is the benefit of the C630 nickel/aluminum valve seats and guides?

These specific valve seats and guides are made from a C630 nickel/aluminum alloy. This material is known to be gentler on the valves, which helps to reduce wear and potentially extend the life of your valve train components.

About this part

Product Details

Cylinder Works is known for making reliable engine components, and this 450cc cylinder head kit for your Honda TRX 450 ER is no exception. If you're looking to rebuild or upgrade the top end of your machine, this kit offers an OEM-style replacement that's ready to install right out of the box.

This cylinder head features an unshrouded combustion chamber, which is designed to help improve airflow. The bowl area has been blended, and it comes with a competition-grade valve job already done. This means you're getting a head that's set up for better performance. The valve guides have been shortened to work with high-lift cams, giving you the potential for more torque and overall power. Plus, it uses C630 nickel/aluminum valve seats and guides, which are gentler on the valves themselves, helping to reduce wear over time. The ports are shaped like the stock ones, but they're designed to deliver high performance.

This kit comes complete with cam caps and bolts, making installation straightforward. Keep in mind that valves, springs, retainers, and lifters are sold separately, so you'll need to source those to complete your build. This is a solid option if you're aiming for improved performance from your TRX 450 ER's engine.
