Any time you install lighter springs, you need to test the revolver carefully. The springs you have chosen should work in a J-frame that is in excellent condition. But if anything is significantly out of spec, then there could be issues. For example, if endshake, headspace, or firing pin length are out of spec, then the lighter mainspring could lead to misfires. And if there are burrs, rough spots or friction, then there could be misfires or problems with return.
All of these problems are unlikely, but it is really not possible to say what springs will work without doing a thorough examination of the gun. If you test the gun thoroughly, it should become apparent whether everything is OK.
