I'm building a 302 w/ gt40p heads in a 1961 falcon. Has anyone used the ford racing shorty headers that fit gt40p plugs? If not, which repo cast iron headers work? does the y style work or just stock one will. I have manual steering and a c4 trans with a 164 tooth starter setup. Has anyone put regular fox mustang shorty headers in a falcon. The fit is most likely very similar to regular shorty headers. I don't want to butcher up the shock towers, but a lil coaxing will be ok.
