1.6 Ratio-7/16" Stud Roller Long Slot Tip Rocker Arms for Small Block SB Chevy-Sold as Set
These rockers are stamped steel and have a 1.6 true rocker ratio with a long slot for extra lift clearance. These rockers are great for stock replacment rocker arms when you have over .500 valve lift. They come with Nuts and Pivot Balls. The roller tip helps prevent valve and valve guide wear by reducing friction at the valve tip.
The 1.6 ratio will give you more lift then the 1.5ratio rocker. You can figure your lift if you know your cam lift.

Stock Rocker with 1.5 ratio .350 Cam lift x 1.5 = .525 lift
