I cant answer your question, but find out the year of the explore. I believe its 95-96.5 are iron gt40's, and 96.5+are gt40p's. The p's need special headers.

if i remember right they are the gt-40 iron heads. and require special headers. ford motorsport makes them

the cr should be the same for them, but Daniel's correct, you do have to get different headers because of the plug angle on the explorer P heads...
correction: the cr will go up a hair with the P heads (aren't they 58cc?), and should stay the same with the plain GT-40's
