The guides and tensioners will need replacement before the chains i would think. I'm gonna do mine next time the cover comes off but i have talked to a few techs who say these chains are very good and still look fine after 400,000 miles on most cars.
I'm not a ford tech but out of the 4.6's i've worked on the only wear I've seen is the stretching of the chains. If your over 100k then, sure replace them, but like if your lower then that, I'd use discretionary judgment.
+1.... when i bought my chains they said the chains are the first thing to go because they strech...
Honestly, just save up your money and do it right the first time.... When i was going to do my PI swap i have brand new cam gears, crank gear, timing chains, valve followers, valve covers, etc. etc. .. .i mean... there's no reason not to... "well i had my timing cover off, but... i was just too lazy."
if your car runs, save your money until you can do it right... if your car is broken down (and your upgrading,) replace the tensioners/guides. If the chains dont look streched, the links all look good, dont replace the chains. If they are broken, you have no choice... i also suggest replacing all the gaskets while you are there... i mean... just replace as much as you can so you dont have to do it again... thats all im saying in this nice long babble...
