2carb40 Posted May 7, 2021 Share Posted May 7, 2021 (edited) They should all be same length. The length determines where the rocker arm contacts the top of the valve stem. If too long or short, the point where the two contact will move off center and the misalignment will affect operation and could cause faster wearing of parts. Let me know if you need to replace and exact length. Robby didnt get all of mine, so I might have the length you need.
