I'd get the 60k set. The 120k has the cam sprockets and other parts that should be fine. Just give it a good visual check.
Here is a place that has the kit for cheaper.
http://www.amsperformance.com/store/...roducts_id=826 It's not as complete though. It doesn't include gaskets and the front main oil seal and a few other parts. But if yours are still in good condition you should be able to reuse the valve cover and spark plug gaskets. I would go ahead and replace the front main seal though because they tend to leak when they get older.
