CBM MOTORSPORTS™ GM LSX / LS7 CNC PORTED COMPLETE 6 BOLT CYLINDER HEADS .700 Product Description:

CBM MOTORSPORTS™
CYLINDER HEADS.

CBM Motorsports™ CNC ported aluminum cylinder heads for the LS series small block V8 engines will unleash the horsepower, torque and performance that your LS engine is capable of. These LSX / LS7 heads are capable of well over 1000hp on forced induction applications. We start with a GM bare casting and fully CNC port all intake and exhaust runners. From there they get assembled and tested before they are packaged ensuring great heads arrive the first time. To compliment these high end 6 bolt heads we use stainless steel valves and Manley Nextec springs. These heads flow nearly 400 CFM!!!
