NEW CNC CHAMBERS - Flows More Air
Makes More Power
CNC Chambers helps the head flow more air by un-shrouding the valves at low and high lifts. Also all the chambers are exactly the same which makes it easier to tune for maximum power. Intake ports flows up to 5% more and exhaust ports over 25% more with CNC chambers which equals substantial increases in horsepower.
Brodix Big Block Chevy heads are designed with 26° intake valve angles, same as stock GM big block heads and accept all standard pistons, intake manifolds and rocker arms.
The exhaust ports are raised .600 higher than stock for enhanced flow and the valve covers are raised to assure no oil leakage.
