The GT40P heads were standard on the 5.0 Explorers from 97 to 2000. They shared some design with the iron GT40 but outflow them with smaller valves. and have no emission ports. Also have a revised spark plug angle towards the center of the chamber. The thing to take note of is the area under the curve in their flow. I run them on my Fairlane because they are like me. Cheap, easy, work very well and they are overweight.
