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 Race-Rite Big Block Chevy heads are designed with 26 degree intake valve angles, same as stock GM big block heads and accept all standard pistons, intake manifolds and rocker arms.
