Thanks Joe
I will drive this as much as possible in the next few months.
I don't suppose it would hurt to let the shop know I am having some issues
I feel pretty confident based on the list of replacement parts and testing that this is valve related. I had the original shop do the valve adjustment so it was down by a qualified mechanic.
I do have another professional mechanic who actually has a corvette with this same engine in it. I might pay him to check the valve adjustment after a few weeks of running
