You will need springs, valve locks (you are bound to loose a couple), valve seals for intake valves (not required but a good idea and they are cheap), valve cover gaskets, and a valve spring tool. Kirban's sells one, but if you use their's weld it up a little as it broke on me on the first spring. After re-welding, it was fine and helped alot! It's an easy job and made a huge improvement in top end pull.
