They say if you tow a lot or drive it hard, the valves will stay fairly clean. Its the low rpms and idling thats causes the valves to build up. And as far as cleaning them, ive heard the only solution is to take the heads off or they may be able to uses that walnut blast with the heads, but yeas, im sure its expensive. And it may not ever even get that bad enough to need it.
But you are right - the blasting with walnut shells is the best method of cleaning. That is a heads off procedure.
Chemical cleaning may be possible - but is less successful.

6.7L has massively stronger internals compared to any of the Ford EcoBoost lineup, which are still great engines. Diesel fuel contains more energy per unit than gasoline. It would be hard, if not impossible, to ever beat a diesel engine in a heavy truck when comparing torque, efficiency, and longevity.
If there was to be an EcoBoost in a Super Duty, I'd like it to be larger displacement (maybe 5.0) but reduced output (350HP, 450lb-ft). This would still provide great towing characteristics but also provide likely better efficiency and longevity.

The diesel is an awful expensive option, and with higher maintenance and repair costs than the 6.2, the gasser is a better option for lots of folks. For me, once you have had either a diesel or ecoboost there is no going back to anything that is NA.

My existing F 150 has a 5.4 My friend has a 2013 f 150 ecoboost, we tow the same trailer a Lance 2285 at about 5600 lbs. we get the same mileage towing, about 9 to 10. but he has way more power and can out pull me going uphill.

I heard a rumor a few months back that Ford was possibly going to revive the 5.8L (351ci V8) but in DOHC TI-VCT form as a middle man engine between the 6.2L and 6.7L strictly for Super Duty use. I guess essentially it would be a bored out 5.0L, more than likely with an Iron block. That would be really cool to see, but I doubt they'll do something like that...More than likely I would expect an Ecoboost engine of some form or another to make its way under the Super Duty's hood.
A de-tuned ''Ecoboosted'' 5.0L would be an amazing option I think. If it made around 425hp and 550lb/ft of torque or so, It's numbers would be comfortably in between the 6.2L gas and 6.7L diesel. But this is all just speculation and wishful thinking I suppose.

This is exactly what I was thinking with the OP. I need something that will pull my TT on the weekends and still be a decent DD during the week for short commutes. Hopefully we'll see something with the 2018 MY.

Manufacturers claim the DI / Port combo has other advantages beyond just cleaning the backs of intake valves. Who knows.
In our family, we have two other EcoBoost products - a 2010 Lincoln MKS with the 3.5 EB, and a 2016 F-150 with the 2.7L EB. Both are awesome motors. But, at what point will coking cause the intake valve to not seat completely and cause the MIL to light up? Cleaning is perfectly possible, but expensive on most DI engines.

The coking happens because the crankcase vapors (oily vapors and blow-by gasses) or vented into the intake manifold and mixed with clean air. I'm not convinced they wouldn't coke up regardless of how you drive or idle it.

As far as the 5.0 with Turbo's that is already being tested and will go in the next GT500 with a 727 HP / 650 TQ quesstimation or so I've read!

The rumor is that a 5.8L 32V DOHC V8 will show up in the Super Duty.
With the last round of contract negotiations, there was 'new displacement for Super Duty' listed as one of the guarantees at an engine plant.
Personally, I'd like to see a small (4-4.5L) V8 EcoBoost in the Super Duty. I think it'd be the best of both worlds (towing and fuel economy) without the negatives of the diesel (higher maintenance and much higher upfront cost). 425/500 would be pretty good numbers in my mind.
