What Are the Benefits?

The key benefits are:

• Massive airflow increase.
• Huge horsepower improvement.
• Cooler exhaust gas temperatures.

Our Comprehensive Service:

Not only are you getting our performance CNC porting, but we are also replacing all your valve guides with our upgraded manganese bronze guides. These guides retain their size, no matter how hot or cold they get. Consequently, this means less valve guide wear and oil loss over time. The following parts are included:

• Upgraded manganese bronze valve guides.
• High-temperature performance valve stem seals.
• Modified cam caps for additional oiling to the top end.

How the Process Works:

We’ve made the process as easy as possible. Here’s a step-by-step guide to getting your cylinder head ported by REV6:

1. Place your order.
2. Receive our shipping label and rebuild form via email.
3. Put your old cylinder head in a box.
