2.9 head bolts re-tighten?

[johnnybronco]

Anyone ever gone back and re-tightened the stretch bolts on your 2.9 head?
Can you mess with a stretch bolt after it has been set? The Haynes manual doesn't say it needs it, but I've been losing a little oil and getting some water/coolant in my oil ever since I put on a new head gasket and I wonder if it just needs to be tightened up after running for a while now.
