A stock hydraulic roller from a 5.2 magnum with .252 lobe lift with the 116 LSA installed at 100-104 would work pretty well. But I expect to see compression numbers in the Briggs & Stratton 3-1/2 hp zone… of course, quality link bar hydraulic roller lifters will eat the budget pretty fast, too. Look in the oil fill hole and see if you can see the rocker arms to let us know what it’s got.
