Originally posted on modulardepot.com This seems to be a hot topic, so I figure I'm doing us all a favor by posting this. So here's a list of parts AND pics of the parts that's needed to swap a PI intake onto NPI heads. First of all, I don't give a 'Kiss Me''Kiss Me''Kiss Me''Kiss Me' if so-and-so did it a different way, or didn't use such-and-such part...this is the way I'M doing it, so don't start in with "oh, you don't HAVE to use that". Sure, some of these you could leave out without any trouble, and several guys have done it differently. But IMO, this is the RIGHT/SAFE way to do it, so here goes. First pic! This shows everything you needI intake, NPI gaskets (2), thermostat o-ring, water pump o-ring, updated coolant/heater tube, updated alternator bracket, updated thermostat housing bolts (2), and the updated water pump nipple that connects to the heater tube. Here's a pic of the PI intake manifold. Here are the NPI gaskets. Here's another pic of the additional parts: big fuzzy cat, thermostat o-ring, water pump o-ring, heater tube, alternator bracket, thermostat housing bolts, and water pump nipple. Finally, here's a closeup of the water pump nipple. Here's a list with the part numbers: *PI intake manifold: not sure...bought mine used *NPI intake manifold gasket: XW7Z-9439-AA *Thermostat housing o-ring: F1VY-8507-A *Heater/coolant tube: XR3Z-18B402-AA *Water pump nipple: F75Z-8555-AA *Water pump o-ring: F1VY-8255-A *Alternator bracket: 1R3Z-10153-AA *Thermostat housing bolts: N811011-S309 A BIG thanks to Randy Stinchcomb for help getting the parts. All of you 96-98'ers who haven't bought this stuff go STRAIGHT to the Parts forum [at www.modulardepot.com] and give Randy a buzz. You won't find a better price.
