Head Gasket?

[19 STROKER 95]

ok so after my 95 has been sitting in the driveway for 3-4 weeks, i dicided to start her up to put a charge on the batteries and relube the cylinders. After starting her up i noticed a pool of coolant under the truck and some was dripping but the wierd thing is it stopped. anyways a week later i started it up again to let her run for a little bit and thats when it started smoking very bad. there wasnt any coolant leaking from the bottom like last time either. Im wondering if maybe a head gasket went or something, any input or comment would be appreciated.
