Pro-X LS Cylinder Heads

Pro-X™ CNC ported aluminum LS cylinder heads will unleash the horsepower, torque and performance that your LS engine is capable of. Engineered and assembled by CBM Motorsports™, Pro-X™ 6 and 4 bolt cylinder heads for LS style engines are designed for 4.065” or larger bores and have LS3/L92 intake ports.

They also feature a raised rocker rail for improved rocker arm/valve cover clearance and are capable of making well over 1000hp. We 100% CNC port all intake and exhaust runners, blend the bowls and match the ports.

 CBM Pro Series Rocker Arms manufactured by Jesel are included with the Pro-X™ complete with rocker arms package.
