Last picture ,Rocker on right you can see where it touched the spring, That little shiny spot on the underside, This is common with HP springs and 318 rockers that were not clearanced as stated above. All 340 rockers are clearanced. Many guys just bolt on 318 rockers and don't check this . The OP at least caught it . As I said , Looks to me like he has standard diameter HP springs and retainers and 318 360 rockers
