I rule out the valve springs because I have been in the valve covers 4 times adjusting valves, inspecting rockers and oil flow and appeared fine. However, I will look one more time.
It also runs fairly smooth, whereas I would expect a valve issue would cause it to run rough wouldn't it?
I have driven the truck around a few blocks and truck drives well.
