i know cobras had the gt-40 heads, but which other vehicles came with gt-40 heads? i know explorers came with gt-40p's but i dont want those because im going with bbk shorty equal and either ill have to ding the headers or use shorter sparkplugs, so which other vehicles come with gt-40 heads, and does anybody have any for sale?

Ecstasy

i believe some explorers came with the gt40's. 96 and down models possibly?

Mustangkiler

those are the p's on an explorer that he does not want

and its 97 1/2 models & up came with gt-40p's btw. lol, but yea i dont want the p's, because the only way my bbk shorty headers would work would be to either ding the headers to fit the boot or use a shorter plug, and i like my autolites and im not switching & i dont wanna ding something i spend $300 on. atleast thats my point of view.

96-97 are the regular gt40s neal they are stamped gt and the gt40p;'s are stamped gtp

Yes, but before 1997 1/2 the came with the regular GT40 heads, not the GT40P heads.

CAUTION..... pre 97.5 GT-40 heads had a larger combustion chamber than cobra GT-40 heads. you will want to get them milled down at a machine shop. tell them that you want a 64cc or smaller combustion chamber after milling. this will get you closer to the stock 9:1 compression ration acheived by E7TE and Cobra GT-40 heads
