So, apparently the rumor that Ford changed the Heads on the 2018 6.7L are incorrect (As a tech looked up the 2017 and 2018 part numbers and both were apparently the same). Are there any changes that anyone is aware of that would point away from the 2017 trucks possibly being able to be software updated to 2018 HP and TQ numbers?
This is would great. I know the numbers are marginally better (probably not enough to matter), but it would be a good thing if Ford did a simple software upgrade to 2017 owner's trucks as part of a TSB.
It's all across the Internet that Ford updated or changed the cylinder heads, including Ford's own press releases. Ford isn't lying. Your tech is either looking something up incorrectly or the info simply isn't updated in Ford's system.

I'm inclined to agree that Ford changed the head based on the statement.
But sometimes manufactures revise a part without changing the part number especially if it is backwards compatible.
Ford produced '17 trucks and the next day they produced '18 trucks - all changes were programmed after
GM released their specs - the engines are computer controlled and can be updated .
A tuner that upgrades John Deere Tractors has a module that fits inline after the ford unit so it does not show
on a scan . Uses a four position switch for different hp increases . Ford will not do this due to warranty costs .
GM released their 2017 L5P engine specs over a year ago, so this is not directly reactionary. Sure, Ford could tune the 2017 engine electronically and make zero changes while increasing horsepower and torque...but in this case they changed the head design. That was done probably in an effort to maintain or improve fuel economy, engine durability, or emissions with the increased power level.
Yes, from one day to the next Ford is producing 2017 trucks and then 2018 trucks. But surely you don't suppose that precludes them from changing the cylinder head design...one day to the next?
I have no idea what you are talking about in regards to John Deere / Ford.
yes and the only reason they did that was because the 11 was an all new motor that Ford needed people to buy. The fact the competition came out with more power shortly after the release of the 11, Ford had to do it to keep the 6.7 attractive.
This is not the case for the 17 to 18 MY. Ford's 6.7 has proven itself and now it is about new sales trumping the competition .

I agree. That power update also came very quickly after the release of the 6.7L Powerstroke. An update at this point for the 2017? The 2017 engine has been in production for over a year...not happening. Besides, it's only a +10/+10 improvement. I highly doubt that will make any difference at all with the power levels being what they are. We're taking about a 2% increase in horsepower and a 1% increase in torque.

???I don't understand what JD tractors have to do with this.?

Agreed.
Engine assembly plants and vehicle assembly plants do not necessarily operate on exactly the same schedule.
Engine plant starts producing and shipping a new engine when it has the parts and when it has the production line up and running.
Assembly plants installs whatever engine it receives from the engine plant.
By way of example, just look at the Navistar change over from the 7.3 to the 6.0. Navistar produced a boat load of 7.3s and stockpiled them. Trucks produced in September/October had engines made in May/June.
With modern Just-In-Time production methods, the two plants run pretty much in sync. But some late production 17s could have received the upgraded motor.
