14mm wrench, and 12 mm wrench,

undo the fuel line off the injector or at least loosen, then unscrew the injector.

On an NA they just pull up but on a turbo they have to unscrew from the head.
Loosen or remove the fuel line as said earlier.

Those should be real easy with all the access room. Use both wrenches at the same time - Put the lower (12mm) wrench on, then the upper 14mm oriented 30-or-so degrees clockwise of the lower wrench, then take them both in one hand and squeeze together. -Then loosen and unscrew the injector with the 12mm. The holder may come out with it - that's fine, otherwise obviously unscrew the holder seperately. Before reinstalling, (if you're going to), clean up all the threads the best you can. +You'll probably find the inner space between injector and holder needs cleaning. The larger holder threads can be done with either a toothbrush or small wire brush and vacuum. Vacuum while brushing the internal head threads to keep grit out of the engine. I put a bit of plumbers teflon lube ("pipe dope") on those large external holder threads to ease reinstallation and lessen the possibility of the threads grabbing and crossthreading or cracking. The torque spec for the holders ("insulating connector piece to cylinder head") is 22-25 Nm or 16-18 ftlb.
Injector to holder torque is 6-7 Nm or 4.5-5.0 ftlb.

Any advice for rooming the head?

Must the entire engine come out of the bay in order to take the head off? I am running into an issue with removing the head where the back side of the hide hits the firewall when sliding the head out and there is still another inch or two of the head studs inside of the head. There's no room or place to try jacking the motor up on oneside a bit just to get the head to angle more towards vertical. Tried jacking the engine up as far as possible without hitting the bellhousing on the firewall still not enough room.

Rumor has it that it can be done on a 931

BUT

rumor also has it that it's easier to pull the motor.

normally the head doesnt have head studs, it normally is just bolts,
however if there are studs, is there an allen key slot in the end to be able to remove the studs from the block?

Unless they changed the design since I got mine, no there's no hex socket in the ends of Raceware head studs. I noticed the possible future problem while installing mine and cut a slot in the top of the studs so a flat-blade screwdriver could be used to remove them with the engine in the car. You might be able to to use 2 nuts tightened against each other at the end of the stud and a wrench to back them out - if you can find room to do it.

This may work:

Remove nuts and washers, lift head as high as you can, and put a small piece of wood between the head and the block to hold the head.

Then use your fingers or a pair of pliers to twist the studs out.
