when i did my MS3, i did new valve springs for its size as well as new retainers and hardened pushrods. I also put in a ported oil pump. It only makes sense since you're already in there. Trying to save a buck just hurts in the long run.
also keep in mind that more power means more stress on those weak '98 rod bolts, and high rpms can blow apart the needle bearing in the stock rockers... goal for more power means more things to address.
