Most of you are probably wondering what I'm up to since I am asking all these questions. I am going to buy all the stuff I need to do what I am going to do them do this project. Anybody know where I could find some of these for cheap? I thought I was going to get a deal on ebay but it turned out to be 4.2 heads. I did a search for 4.6l heads and that came up. Click on it to see the buy now price and it said $50. That included valves and everything. Then I noticed they were for the 4.2. The topic(for lack of better word) even said 4.2 but when I did the search the topic said 4.6?
