Still sounds like it's running hot,.mine stays right around 180-190, make [censored] sure that the radiator shroud is there and that the fan is half in half out, everyone I know that removed their radiator shroud on a Pontiac because it looks cool started having over heating problems, still if you're motor was over heating you'd hear it when you shut it off, and it should be puking out the overflow.
I also use Water Wetter, I don't even run hot on 100 degree days
