Extensive CNC and dyno testing has resulted in one of the most affordable and powerful LS7-based cylinder heads available! Flowing up to 53 CFM more than the stock GM LS7 head, the all-new PRC cylinder heads offer both unmatched power and airflow! The 285cc runner is recommended for higher HP applications with a minimum bore size of 4.125".
The PRC LS7 285cc cylinder heads are available with hollow-stem or titanium intake valves. The hollow-stem intake valves shed significant intake valve weight and allow for additional lift. The titanium intake valves will be the lightest choice however and offer the best durability possible!
