Here's the info:
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 (all)
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 and modified alignment feature
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.

That's how mine started .... Ticking coming from the passenger side. I checked the first 3 closest (easiest ) plugs and they were fine. I was running late and didn;t get to the back 2 --- next day --> guess which one blew ! $300 tow to Ford for them to cover it under warranty ....
Definitly check them and take a peak at the studs as welll... Mine is a 2000 and being in the northeast doesn't help the rust factor either... Mine's got a couple missing - but still not a real problem... will look at getting them replaced in the next few months while still under warranty
good luck !

Alright guys, I just got the best news to report. After trying to find the ticking noise I started with the many suggestions from this site, start at the plugs was what I did. Well guess what, it was a plug. I was lucky enough to hear the ticking soon enough and stop driving it. The plug was just about hand tight. I removed it carefully and no threads had any aluminum on them so I feel pretty safe that I was lucky enough to catch it. So I torqued the plug back down, and the ticking is gone. I want to thnk the people that posted on my thread and also for the awesome site. Thanks Todd
