SBC H/E Alum. R/A's - 1.6 Ratio 3/8 Stud

The COMP CAMS SBC H/E Aluminum Rocker Arms with 1.6 Ratio and 3/8-inch Stud Mount deliver high-energy performance for small block Chevy engines seeking increased valve lift and duration. This 16-piece set provides full roller rocker arm assemblies engineered to maximize cam profile utilization while reducing friction across the entire RPM range. The die-cast aluminum construction balances weight savings with structural rigidity, making these rocker arms a preferred upgrade for both street and performance applications.

The 1.6 rocker ratio multiplies the cam's lift output, allowing builders to achieve higher valve lift without larger cam lobes—a critical advantage when working with existing blocks, head geometries, or compression constraints. Full roller design minimizes wear on both the pushrod seat and valve stem tip, extending component life under sustained high-RPM operation. The 3/8-inch stud mount interface provides secure, repeatable installation on standard small block Chevy cylinder heads, ensuring consistent valvetrain geometry across the complete set.

These rocker arms suit builders upgrading stock or mildly modified small block Chevy engines where increasing effective cam lift improves airflow without requiring full valvetrain replacement. The combination of die-cast aluminum and roller technology makes them ideal for street performance, mild race, and restomod builds where valvetrain reliability and ease of installation matter. Proper adjustable pushrods and quality pushrod wear sleeves are recommended to ensure optimal performance and longevity in this application.

Small block Chevy rocker arm selection directly impacts cylinder head flow characteristics and overall engine breathing. The 1.6 ratio positions this set as a popular middle-ground choice—offering meaningful lift multiplication while remaining compatible with most bolt-on upgrade paths. Verification of rocker arm geometry clearance with existing pushrods, valve covers, and aftermarket intake manifolds is essential before installation.
