@Tractorman I don't know if they have the exact order.

@LorenS I appreciate it, yeah i am going to have them check it before putting the head back on the truck as that in another $1000 just in labor and parts that I'd rather not spend if the head is no good.

Well finally drove the old goat home today.

After testing the theory of the injector feeder tubes holes being off by a few degrees we were able to see that this was most likely the case.

The same uneven scoring on the tips happened when using one of the tubes from the front on a cylinder on the back of the block.

 

From here we ordered a new head and within 2 weeks the truck was up and running.

 

So lesson learned, if you buy a new head not only check the vales and all of that fun stuff but also dry fit the injectors and feeder tubes before putting it on the truck.

 

I want to thank everyone on here for your input and suggestions throughout this post.

Now let me ask... Which did you tighten first? Injector or the lines? Lines are to be tighten first before injectors. This allows the injectors to move a bit to line up the crossover tubes in the injector sockets and make the best seal.

When testing the back 3 cylinders we set the injectors then tightened the feeder tubes then tightened the injectors down.

 

The first test showed the seating was off so the shop got a thicker washer for the injector and that still did not help.

 

At that point I did not want to take the risk of putting the head back on it since it was out of warranty so I decided to just go with a new one that way if there is an issue we can warranty it and they pay for the extra labor.

 

After all of this though it has made me more aware when doing anything with the injectors again.
