Here's a link I thought absolutely addresses changing plugs in Modular motors very,very well: https://www.ford-trucks.com/forums/1...ed-torque.html
Look at post #2---great general advice IMHO.

A bit irrelevant since his Excursion doesn't have the 3V.
--------------
However, the 01 V10 in the Excursion should have the long thread heads, IIRC. That's the biggest issue with plugs and the V10. Early models had the short thread heads and sometimes they would spit out plugs if the torque was incorrect.
Plus, #10 is a bit of a bitch to get out. Make sure you have a U-joint or two for your socket set. I would always do that one first. The rest are easy.

The longer threads actually came in 03.

Running spark plug changes:
December 1996 - 4.6L 4V alignment feature added
February 1997 - 4.6L 2V head alignment feature added
September 2000 - WEP (Windsor Engine Plant) 2V head alignment feature modified (4.6/5.4/6.8)
November 2002 - WEP introduced long thread heads on 2V (4.6/5.4)
May 2003 - REP (Romeo Engine Plant) introduced long-thread heads on 4V 4.6 and 5.4
November 2003 - REP introduced long-thread heads on 2V (6.8) and modified alignment feature 2V (All)
In 1999, and 2001, an interim fix was done for a cross-threading issue.
Original process:
Step 1 - Zero torque spark plug (air tool)
Step 2 - Torque to 16-20Nm final torque (DC Run down), monitor at 6-12Nm, and final torque must be reached within 0-360 degrees.
New process (addressed the possibility of applying installation torque for more than 25 degrees of rotation)
Step 1 - Zero torque spark plug (air tool)
Step 2 - Torque to 16-20Nm final torque (DC Run down) start monitor at 6-12Nm, and final torque must be reached within 3-25 degrees.
Another action to address cross-threading was the addition of an alignment feature to lead the plug into the hole. <!-- / message -->
