RE: heads
gt40 irons are from cobra's
gt40p are from explorer/mountaineer.
the cobra stuff is better no matter what anyone says, thats why it's cheaper too.
gt40p require some modification for the headers to work, the spark plug angle is different, and the explorer intake you'll need to tap and drill for the temp sending i believe.
the cobra stuff will get to you move, don't do it all stock, port the lower intake, port the exhaust ports on the heads.
you'll see a nice gain for low $$$$$
