The process should be the same for both engines. You only want to use OEM glow plugs, the others swell up over time and won't come out of the hole that they're in.
Remove valve covers, loosen the glow plug but only enough that it's loose because the rockers won't let you completely remove it with the socket attached. Then get a piece of fuel hose and slide it down onto the GP to finish unscrewing it.

Other than removing the Charged Air Cooler tubes on a Superduty - there is almost zero difference in the procedure. Loosen (do not remove) the GPs with a 10 mm 1/4" drive deep socket with an extension for best results to get by the rocker arms. Then, I use a 5/16" semi-rigid plastic fuel line for removal and insertion.

Save yourself some frustration and pick up a 13mm flex socket. It makes the valve cover bolts next to the HVAC box and at the rear a lot easier to deal with.

Just a friendly reminder. It's a must to evac all the oil surrounding the GP in the cavity of the head. If you don't, the oil will run into the cylinder and may cause a hydro lock condition.
I used a minishop vac and fashioned a small tube on the en of the hose to extract the oil prior to pulling the GP.
The rest is pretty straight forward.
On a side note: If your already under the valve covers. A re-torque of the injector hold down bolts should be on the list.
Rich and others can tell you how to/and with what tool, to properly complete that procedure. I did it a few years ago and my bolts were very loose. It completely changed the performance and sound of the engine. Well worth doing say 20 minutes.
I thought there was a sticky for both. But I can't find it. I'll check riff raff's page and get back.

Not really. The only trick is to have a good assortment of socket extensions, swivel ends and maybe a u-joint for getting to some of the valve cover bolts. Other than that, a decent set of sockets and hand tools and you are OK. My first glow plug job took 3 hours, with me taking my time and fumbling around for the right socket extension combos. The second try was half time. It looks more intimidating that it really is.
