The conical valve springs with higher spring rate and the lighter weight of valve train components result in sharper response and eliminate valve float under high engine RPMs. These stiffer springs have an installed pressure of 125 pounds and handle 60+ psi of boost. All valves are fully nitridated and Stellite-Alloy-reinforced for superior durability and reliability.\u003c\/p\u003e\n\u003cp\u003eThe spring retainers and seats are made of high-strength chromoly steel to handle the increased spring pressure.
