They will fit most, small block Non-Hemi style heads on 196 Clones, Tillotson 196/212R/225, Ducar 196, and Non-Hemi Predators. We recommend using these rockers with camshafts less than .235” lift with up to 22lbs springs. If using bigger cams or stiffer spring may cause the rockers to fail. These rockers are great to use on a stock lift or mod2 camshafts to get the results of bigger cams at less cost. 1.3 ratio rockers add 30% more lift to the cam and can greatly increase the acceleration of the valves. Stock lift .223” with 1.3 Ratio Rockers equals .2899” Overall lift.
