So here is how I am seeing it.
Your motor is running hot after our $9200 long block rebuild and we have determined that it was caused by this cylinder head that we rebuilt already but not the other head. This head had a blockage, (CRACK) that there was no way we could have known. (WE MISSED THE CRACK)
We will not stand behind our motors because there is no way we know how they will be used. (OR HOW MUCH DAMAGE WE DID WHEN WE GOT IT HOT)
Also, (YOU SHOULD TRUST EVERYTHING WE DO BUT WE DO NOT TRUST WHAT YOU ARE GOING TO DO)
