I have a 306 with a e303 cam and gt-40 p heads that I plan to put into my 92 2wd. Does anybody know what headers will clear the angled plugs on these heads. I know that there is no advertised gt-40p header for the f150, but I know someone out there has these heads on their truck. Im thinking that I can use the mustang shorties, and re pipe the rest of the system to fit the mustang shorties, any inupt will be greatly appreciated
