They may cause more problems then they are worth. You first need to set the wipe, can't just bolt them in. Once you do that, then measure for pushrods. Once done, you have to have enough spring to control them and if your springs are stiff the 5/16" pushrods will be flexing and you will need larger OD pushrods to keep things in control.
