The way that you describe the probem, is the same thing that I went through two years ago with my 360. I had the 14 year old valve springs replaced. End of problem.




That would mean the springs in MrBelvedere2's motor would have not be new. And really shot old springs at that. Maybe pull some valve springs and get them checked. And check if the valve guides are hanging up the valves.
