Perfect for initial break-in, these Ultra-Gold ARC rockers for Chevrolet Small Blocks reduce valve lift by limiting the rocker ratio to 1.3. A great asset to engine builders who prefer to limit the valve lift over removing an inner spring.
These COMP Cams Ultra Gold Aluminum break-in rockers are designed with a lower-than-stock ratio to help break in new Chevrolet V8 Big Block applications. They are engineered to eliminate the excess open spring pressure, making them a must have for the break-in process. If you've got a new big block to break in, no other cams will help you do the job better than these COMP Cams Ultra Gold Aluminum break-in rockers.
