Dart BBC 335cc CNC Pro 1 Bare Aluminum Cylinder Head

Description

When you want CNC precision and big airflow without going to extreme runner sizes, Dart’s 335cc Pro 1 heads are the perfect foundation. Built for Big Block Chevy racers who demand control over every component, these bare aluminum castings let you spec your own valve train for maximum performance.

Features:

• 335cc CNC-ported intake runners for strong airflow and velocity

• Bare aluminum casting – choose your own valves, springs & hardware

• 121cc combustion chambers for versatile compression setups

• Fits Mark IV Big Block Chevy engines (396–502 ci and larger builds)

• CNC machining ensures repeatable flow numbers across all ports

• Lightweight aluminum design reduces front-end weight for better weight transfer

Why It Wins:

• Medium-large runner size = excellent balance of torque and high-RPM horsepower

• Bare heads = freedom to match your exact cam, springs, and valvetrain needs

• CNC porting = consistent, track-proven airflow

• Aluminum weight savings = quicker launches and sharper handling
