Flowing up to 35 CFM more than the stock GM LS7 head, the all-new PRC cylinder heads offer both unmatched power and airflow! The PRC LS7 cylinder heads is available with standard stainless valves, hollow-stem intake, and titanium intake valves. If you are going to run the stainless steel intake valves, we recommend limiting total valve lift to no more than .616" due to the weight of the intake valve. Upgrading to the hollow-stem intake valve will shed significant intake valve weight and allow for additional lift. The titanium intake valves will be the lightest choice of the three choices and offer the best lift possible!
