  1. my next project is sohc<dohc. That being said, I got a '01 expedition 5.4 in my car now, wanna supercharge it, wanna dohc it...
    My question is, if I use navigator heads will the newer Shelby lower intakes fit or whats the basic run down on it. Or do I gotta get gt500 heads for it to work right.

    5.4'd and loving it.
