What is the primary benefit of using a 1.8 ratio rocker arm?

A 1.8 ratio rocker arm effectively increases the amount of valve lift compared to a stock ratio. This allows the engine to breathe more freely, potentially leading to improved performance, especially at higher engine speeds.

What specific components are included in this kit?

This kit includes a full set of 16 Ultra Pro Magnum rocker arms with poly locks, 3/8" studs, and raised guide plates. It is designed to work with 5/16" pushrods, providing a complete adjustable valvetrain solution.

Do I need any special tools for installation?

While the kit itself provides the necessary valvetrain components, you will need standard engine tools for installation. It is recommended to consult the manufacturer's installation instructions for specific guidance on setting valve lash and any specialized tool requirements.
