Steps to remove cylinder head - 3.4 996

[TNT79Bronco]

Long story short, I have a good 3.4 engine, that has an EZ out broke off in one of the heads.  Someone tried (unsuccessfully) to remove the exhaust headers, and twisted off a lot of the bolts.  In the process of trying to rectifying the situation, they broke off an EZ off in the bolt they were trying to remove, and now we are in a pickle.  It is a large EZ out and almost the size of the bolt. To remove the EZ out/bolt, the head needs to come off and mounted in a milling machine.

 

So, I have removed heads off a Ford 460 and rebuilt that engine, but wanted to know what I was getting into as far as trying to remove the heads off of the 3.4.  I would love it if someone could break down the process and let me know how difficult it is.  The machine shop doesn't want to touch removing the head.  They just want the head off of the engine.

This would be infinitely easier with the engine out of the car as a lot of the things you need to get at and remove first are going to be difficult otherwise.

Engine is already out of the car.

Then it is pretty straight forward, the intake has to come off, as well as any serpentine driven items.  You are going to need cam retention and cam timing tools to get the cams out without breaking them, and a copy of the cam reallocation process to reset the timing when you are going back together.

Hello all...getting back to this project.  I assume that this kit has all the items I need?
