As the title says Im wondering what years did the GT40 heads come on the explorers. . . and did they only come with gt40p heads or did some come with the gt40 heads?
Also i just bought new BBK shorties for my stock heads. . . will these work on a P head? i heard the plugs are hard to get at on the p heads, but could i slap a new set of plugs in and next time i need to change em drop the headers.
thanks

 

I believe it was the Eddie Bauer Editions only in 93,94.
