The V-10 is a great engine. Love my '04 F-250, no issues of any kind. The cylinder heads were changed to a different design late in the 2002 model run to address the plug thing. The earlier heads have three threads to hold the plug in place. Late 2002 and up heads have seven threads. Much better design. I chose my 2004 partly for that reason, and I wanted the Dana 60 front axle, which became standard in 2003, I believe. I did not want the coil spring front suspension that came on the '05 and later models. Narrowed it down to an '03 or '04, then started my search from there. Make sure your plugs are torqued to 11 ft. lbs. and you should be fine.
