When you contacted us the first time about the head gaskets being installed wrong, my engine builder didn't want to believe that he had done such a thing. He does know how to install head gaskets! When we saw that he had done exactly that, we admited to it and was wanting to work out what would be the best policy to make you whole again. You was the one that said (No problem I will put new head gaskets in and just send me a bunch of shirts, sweaters and hats etc.) We sent them. The next problem you called us about was this cracked head problem. We told you our warranty policy that includes you sending the engine back for us to diagnose the failure. You said that you would do so. We have never received the engine back for warranty consideration. We do need to see what failed and why. We and Randy are very honest people and would take care of any warranty that is ours. You have not given us a chance. You now have someone else cutting the head apart. We have worked extremely hard in cutting heads apart mesuring were we can do porting and where we should not. The reaserch that we put into what can be done was extensive. We port our heads on a CNC Porting machine. This is light years better for porting heads consistently. I am not saying that we are perfect. I am saying that we have not been given a chance to see the failure. You have NEVER talked to me about this. I have to have a good customer email me and say you should read this thread.
Thanks, Brady Williams

Brady, the cylinder head is NOT being cut apart. If you read my original post's correctly you will notice that i have another head cut apart that was cracked 4 years ago. It is in no way shape or form a II head. I will NOT cut these heads apart to reverse engineer them as you seem to think i will.... why would I want a port design that cracks????
I also notified you guys about the spring retainer issues, the scratches in #8 piston, and the valve lash issues found upon initial disassembly. I did agree to the t shirt thing for cost of head gaskets FOR SURE, it was my idea since gaskets would take for ever to come across the boarder.
You have PM'd me to call you..... i have told you twice now that i have lost my job over my attitude towards this hobby ever since these motor issues, and I dont have $100 to spend on a phone call to SLC. This is my fault i know, but its also reality. I hope you can understand that. I got hit with a $450 cell phone bill just for taking a few pics and sending a couple text messages when i was in texas for the world finals.
I also told you that nothing in this diesel world seems to be a big deal until its on the internet, this is just another prime example of that.
I apologize for it coming to this, i have defended your company in the past when others slam II, now i guess im no better than them. I still run your decals on my truck and get tons of comments on the truck and decals. I assure you the port desing is not being copied and the heads are completely in tack sitting on my tool box in storage until i find a job.
As far as the guy that installed the gaskets wrong? Over the phone he told me he does them all that way, even looked at another in your shop at the time and verified. Spring retainers? I was told you guys pulled valve covers off another motor there and verified how loose the retainers were on that motor too. I beg you to look into spintron testing of valve trains, youd be surprised how much these things move when under RPM. You could probably build even better motors if you adapted this testing into your current program. Im glad i was able to teach you guys about duramax cylinder head gasket selection and hopefully proper valve train components in the future. The hmmmm's and haaaaa's over the phone when i called about these issues 7 months ago verify ya'll being unware of the proper procedures.
This pretty much covers everything i was going to respond to your PM with, just found this comment tonight after i got home from looking at a nostalgia fuel funny car to work on next summer.
##edit## forgot to mention about contacting II about the issues with the injector bodies also.
