95 4.6l pi

  1. 1995 Cougar What do I need to do in order to do a PI head swap on my 4.6l?

    4.6L Tech
    I currently own a 95 cougar with the 4.6l. I have seen many people put the PI heads on the 96 and up engines, but i didnt know if i would need anything special for the 94/95 engines. anything different than the 96 swap?
