Okay, the dealer has the new head and head gaskets to put on my motor and I was wondering how many hours does it take to do the job. The old head is already off so they probably need to transfer parts from old head to new head and install on the truck. I really want my truck back and they are open on Saturday. They intially said they were going to wait till Monday to start on it, but I want to push them to start now so I can get my truck back tomorrow. Is that time frame reasonable?
