Change the head bolts, it's not worth the risk.
If the gasket goes again quickly, I'd say that head was not torqued down correctly. A warp in the bolck or head would generally take a little longer to cause problems.
Anyhow, when changing the head gasket, spend a extra $80 or so and get the head checked/ pressure tested, and a 'clean up' shave.
CAUTION: Slippery When BOOSTING!
