The TimeSert inserts I have replace the original casting four threads with four threads in the insert - kit is 5553 with inserts 51459.
You can refer to the TimeSert website to determine if your head castings might be candidate for their second option, replacing the original cast four threads with full length threads - this is a different kit and different inserts.

The inserts are stainless steel and have 4 threads which is sufficient.
I just looked thru the Timesert website and don't see an optional kit.
Do you have the part no.?
There is a kit that has what looks like 8 thread inserts for the 3V heads which use M16 plugs.

I have the Timesert 5553 kit and repaired #3 on our 6.8L with it.

Always use anti sieze on the new motorcraft plugs.. not alot. you dont want the plug to corrode in the hole. torque to spec its not much. Timesert works well no need for new heads imo. I never lost a plug. maybe someone over torqued them and weakened the threads although they can take alot of torque.
Use the Timesert, CalVan, or Lock-n-Stitch to repair any blown holes. Do NOT use the Helicoils!!!
Put plugs in DRY, do NOT repeat NOT use anti-seize on the moduar engines, it screws up the torque which contributes to the risk of blown plugs.
Torque to 26-28 lb-ft, double the factory specification. You'd have to go beyond 100 lb-ft to damage the threads.

Been here since 2003 guys Use the antiseize and all will be good. They are not torqued much so a little lube wont hurt the torque..I'll bet 99 % of us has been using anti seize on the motorcraft plugs all along. Motorcraft recommends it. I've been reading it for years. 1st time I've heard of someone saying don't do it. To each his own I guess.
I did the same 25-30k ago and blew a plug March of 2016. After that I upped all plugs to 25 ft-lbs.

Motorcraft recommends it.
I agree with the kits you mention to use but disagree on the Heli-Coil exception being the Sav-a-thread. See picture below. It has the stiching like the other kits.
Also, see ++ TIME-SERT KITS ++ helicoil save-a-thread failure Spark plug blow out spark plug blown out The insert you indicated gets a special mention.

I didn't give you a citation. I just told you where to go get it. Did you ask ?
I am on my second vehicle with the V10 in question. Both have done great with 25 ftlbs of torque on the plugs, just like the Ford mechanic told me. But what do I know, he only has 25 years of service. I guess this forum is more reliable.

Personally, I recommend 28 lb-ft, but I also know it is not a Ford recommendation.
Getting information for a "Ford mechanic", an employee of a private business that is not Ford but is a franchisee, is certainly not the same as getting the information from "Ford", the company. If "Ford" issued information that changed the specifications that were previously published, it would be in the form of a TSM, SSM, or the like. That would be a citation of an official source. If they have issued one, it would be news to pretty much everyone around here.
There is a distinct difference between an anecdote and a citation from the official source.

So I conclude from what you are saying that Ford garage (not independent) are STILL tightening the plugs to 11 ftlbs( or whatever the torque amount was that they were set at initially) on these engines?
I seriously doubt that.
