I was thinking rather than replacing them I would coat them with anti-seize so they won't rust as badly. Suggestions?
Try a compound called "Never-Seez." It comes in a small can, and possibly in stick form also. You merely apply a small amount to the threads of any stud, spark plug, etc., and it makes removal a snap. You might also want to check Youtube for tips. IIRC, I ran across one that had to do specifically with the type of bolts to be used, how to torque them, etc. but I didn't save the link. Another thought: find a forum that has to do with Fords and toss up your question to the forum members.
Regarding the rust, I use a small wire brush to remove rust, or soak them overnight in a liquid product called "CLR." It also removes calcium and lime. I'm not familiar with using stainless for head bolts; it depends on whether or not stainless bolts are prone to stretching when tightened. I am also not famiiar with how to prevent regular bolts from rusting, once they are installed.
