pull the injector cup first and replace it. also i would be weary about the number 6 connecting rod making an exit in the future.
i remember hearing quite a few guys hydra locking a cylinder and with in 6months or so of each persons hydralocking, that cylinders rod made a nice window.

I dont mean to scare you but it doesnt take much to bend a rod in this kind of situation

...I'm curious as as well. My truck is sitting in the garage with bad cups and I'm driving my backup vehicle until I can figure what the heck I should do to fix it...

went to IH and got cups put in now im wating on gaskets and head bolts . ill have then tues. morning. i talked to ford and they wanted $200 just for labor. IH charged me $88.50 and $9ea on cups . took about an hour for them to put them in with the head off the truck. i also looked at the coolant i drained and it had a small amount of diesel with is normal. i talked to the guys at IH about the hydralocking and the spent rod issues and they said they have had truck hydralock before and no problems after with the rods.

do a deck height check on your piston with the head off!!!!! This will tell you if you have a bent rod or a crushed rod bearing. simple check to do if you or someone you know has a magnetic base dial indicator.
