Description
Rocker arm ratio directly impacts valve lift and duration, making these S1005-250 units a critical upgrade for any serious small block Chevy build. The 1.6 ratio strikes an ideal balance between valve event duration and spring pressure, while the full roller design minimizes friction losses and extends component life. Orange anodized aluminum construction delivers proven durability at a weight savings that matters on the dyno.
