School me on the V10

I don't have a definitive answer of how to tell for sure but the VAST majority of V-10 EXs did NOT have EGR. Even the Cali spec ones like my '05 don't have the EGR system.

Use the '99 motor intact, and replumb whatever you have to.
Your wife will not care about the power difference. The big problem with the non-PI head V10 ('97-99) was that it would run out of torque early in the higher RPMs. If you were towing with it, you would find that there was a dead-spot in terms of a certain speed where you couldn't keep pulling up a long hill and it would eventually wind up downshifting into 2nd, speeding up a little, shifting into 3rd, and then running out of steam again, and repeat.
For the record, ALL '97-99 V10s are 2-valve, non-PI head/intake. 2000-2004 F-series, and 2000-2005 Excursion are all 2-valve PI-head. E-series V10 from 2000-up are 2-valve PI-head. 2005-up F-series are 3-valve.
Caveat: I've read that you can put a PI intake on a non-PI head, but that was for the 4.6L - while the V10 has the same port shape as the 4.6L and 5.4L (PI to PI, or non-PI to non-PI) I have no idea if the PI intake will work on a non-PI V10 or if it will help or hinder it in any way.
Good luck with your project, and keep us in the loop

The only issue I know of is the later engine got a few more threads in the spark plug holes to help with the plug blow out problem.

In 02 they also switched for the gem module to the vehicle security module I think its called though still no pats system except excursion till 08 and the switch to the digital odometer also happened in 02 not sure what if anything that changes motor or sensor wise though like ford merc said the only actual difference on the motor I know of is the additional threads in the head there have been some guys on here that have said their 03 v10 still only had 4 threads in the so if that's true that could mean the additional threads didn't show up till job 2 of the 03 model year but I have no way of know that for sure
