Their roller tip reduces friction, while stiff design and superior ratio accuracy yield more effective valve lift. With a 15 to 30 horsepower increase over other rocker arms, Magnum Roller Rockers are perfect for performance applications with less than 350 lbs.
Have used these for years in my Vettes! If a person stays with stock ratios a SMALL HP gain can be expected along with a bit more rocker "Music." For pretty much stock applications, I highly recommend this product.
