5.4 GT40 Heads??
the GT40 heads came on the explorer 5.0's but i forget what years. you can also get them from ford racing, but alot of people in the mustang crowd just go to a junk yard and pull them off the explorers and slap them on thier stangs. they flow better than the e7's stockers. this guys has the wrong car and engine, as said before those are just non-PI (in other words, junk).
