What is the primary benefit of using a roller tip rocker arm?

Roller tip rocker arms reduce friction at the valve tip compared to standard rocker arms. This can lead to improved valvetrain stability and potentially a slight increase in horsepower due to reduced parasitic drag.

Does this kit include everything needed for installation?

This kit includes the rocker arms, pushrods, studs, and guide plates. It is designed to be a comprehensive package for upgrading your Oldsmobile 455 valvetrain. Always refer to manufacturer instructions for any additional hardware or sealants that may be recommended.

What is the ratio of the rocker arms in this kit?

The rocker arms in this kit have a 1.6 ratio. This means that for every 1.0 unit of movement at the pushrod, the valve will open 1.6 units.
