Throttle body, accelerator cable, EGR valve, EGR tube, vacuum hoses, fuel rail, alternator bracket, intake tube. That's just off the top of my head. For that price you can buy a low milage PI motor that already has most of that.
Not worth it, better off swaping the whole engine. Buy a 2003 Explorer/Mountaneir and done deal, you'll spend the same amount of money that if you only change the heads and intake, plus, you'll reduce your weight by 75lbs.!
