If you want to use the cast aluminum cover, that's a different discussion and a personal choice. Like other things, there will be pros and cons and you can find those if you search a bit.
If you want to use your stock valve cover, then please go down to a post in this same section from a couple of weeks ago titled something like "Banish Valve Cover Leaks Forever." It should be about 10 or 15 posts down from this one. All you need is a saber saw, a metal blade, a file and some 3/16" aluminum you can cut into pieces from templates you'll make. Then some slightly longer screws (I got them at True Value) and you'll be good to go. You might be able to use the spreaders for the V8 engines, but the best way (if of course you prefer to use your stock valve cover) is to straighten the valve cover out completely, use a new gasket and apply pressure from end to end of the valve cover. Good luck!
