PRC LS7 CNC Ported Cylinder Heads on SALE!
Introductory price!
More air flow, more horsepower, more torque. We take a new set of stock GM unported LS7 cylinder heads and have the latest PRC pro series CNC ports machined into the exhaust and intakes runners for increased airflow. An increase of over 30cfm of intake airflow and plus 20cfm on the exhaust side. Engine dyno testing between the stock GM CNC ported LS7 head and the new PRC pro ported CNC showed an increase of over 30-horsepower! If you want to wake-up your Z06 or you have plans to build a big-bore big cubic inch LSX engine then you need a set of CNC ported PRC LS7 heads. LS7 heads require a minimum of 4.100” bore diameter. These heads are an excellent choice for any big bore, big cubic-inch LS engine!
