I tried all of the quick "tests" for checking for a bad HG and all of them said I didn't have a blown head gasket until I did a leak down test. The second I pressurized cylinder #3 I had air bubbles coming out of my radiator.
I'm not saying for certain you have a blown HG but its a possibility. If you want to 100% rule it out or confirm it, do a leak down test.

AGREE thegipper... I think the HG should be looked into. Any white smoke out the tail pipe (step on the gas peddle and look)? Any white gunk in the filler cap? Bubbles in the radiator with cap removed when running at idle? Coolant level dropping a little every week?
