I read on Edelbrock.com that the E-Street heads (p# 5090) for Chrysler Big Block engines will only use stock rockers and push rods with a stock cam. For a street build, I would have guessed that if the lift was under .500", stock rockers would still work, regardless of whether the cam was technically stock. Has anyone tried these heads with a mild street cam that had more lift than stock? I really don't have money for adjustable rockers and my plan is for a cam with .470-.480 inches of lift, so I don't think I need an adjustable rocker set up. What do you think?
