    Are the GT-40 heads a direct replacement for a 5.0?

    Will the GT-40 heads work as a derict replacement on a 5.0 fox?
    I have seen that the GT=40p heads don't fit without some changes so I'm
    not going to run them. Just need info on the GT-40
    Thanks

    You can also go with a set of 351W heads and use the standard headers. Just so happens I have a set in the classified section!

    Most headers fit fine with P's. Some no-name long tubes fit fine on my truck with P's, just needed to use a couple 90's on some plugs.
