The Edelbrock #5770 valve spring locators are hardened components sold in sets of 16 to positively locate the base of valve springs and prevent unwanted movement against aluminum heads. Intended for big-block Chevy and Ford applications, these locators provide a durable interface between springs and heads during assembly or rebuilds, improving spring alignment and seating consistency.
