I have looked into it the TSB is for 2001-2006. When I had my heads machined I expressed this issue to the machinist and he said that he could pressure test them to check for this issue. I drove the suburban about 45 minutes yesterday and when I came back home it had pressure in the upper radiator hose, not hard pressure like it should have but was better than normal. It was up to temp on the gauge as well.
