I just have to ask, "do you really believe what a dealer tells you."
Whether there is a problem or not with the cylinder head

"GM has told them to replace the entire head and everything related and update the computer code to fix the lean problem They have also been instructed to send in all replaced parts for them to examine."

Sending back parts can be a standard procedure, depending upon the parts. I haven't checked, but I'm sure this part is considered a core return part.

"He told me that the head has to go into a machine shop to get worked when they get the parts."

Now, I'll be honest, this line makes me laugh. If the dealer is getting a new head, there is absolutely no reason for them to send it out to a machine shop when received. The head will be ready to install right out of the box.

"I wish I had never bought my H3. I shoulda known better."

I guess all other trucks/SUVs/cars, etc., can never break...damn, wish I had known that.

Excuse me, but for some reason, I have a hard time believing a first post with the statements you have made. Either this is a troll post, or you are exaggerating the problems, or the dealer is really in bad shape.
