Injector hold down clamps
Just luck, today I found two important pieces of information, just at the right time.
I watched Diesel tech Ron, and he said there are two types of injector hold downs for 6.0l. I just searched the web and some people say don't waste the money. Guess what? The two hold down clamps are not the same in the sense of height. So watch out.

Ford's recommendation for hold-down torquing is 24 ft-lbs for the 03 to early 06 hold-downs, and 26 ft-lbs for the commonized engines. That is 32.5 and 35.25 NM respectively. Many people just do them all to 27 or 28 ft-lbs.
There are some posts about some of the head cracks being connected to over-torquing these hold-downs.

Namnguy, you needed to spend more time getting familiar with this truck before doing some of the things you’ve done.
Anyway the commonized heads that use 20mm dowels take the different hold downs, the injectors are not different. And as Mark pointed out there are a few machinists that attribute cracked heads with over torqued injectors.
