When building a high-output Small Block Chevy using Dart 13-degree cylinder heads, valvetrain stability is non-negotiable. The T&D Machine Shaft Rocker Arm Kit is crafted from premium steel to provide the structural integrity required for extreme racing conditions. Featuring a 1.65 intake and 1.55 exhaust ratio with a 0.650 offset intake, this kit is specifically designed to handle the aggressive camshaft profiles found in modern competition engines.
The steel construction offers superior fatigue resistance compared to aluminum, making this the preferred choice for engines with high spring pressures and sustained high-RPM operation. By utilizing a full roller design, these rockers minimize parasitic power loss and reduce heat buildup in the valvetrain. This kit is the perfect solution for engine builders seeking to maximize the potential of their Dart-headed SBC build. Ensure your engine performs at its peak with the highest quality components from GGCRACING.
