Save an old set of stock valve covers. Why you ask?
Just a tip for those guys who might have to set there own valves. The first time I had to set my own valves a mechanic friend of mine helped me out. He brought over the clips that cover the oil holes in the rockers, however the oil still poured out on the engine and the floor. I told him there had to be a better way, so I took an old set of covers off the shelf and cut exact fit holes over the studs and took an import socket tigged it to an extension so it couldn't fall off in the covers and never spilled a drop of oil the next time I did valves. I don't know if they sell something better than the clips to do this job but for what it cost me I prefer the old covers with the holes.
