head gasket or intake gasket?

the car was misting at 58 degree weather for 10 minutes, i had my hand behind the pipes catching the fluid coming out on my hand. couldnt smell gas or even taste it. when i came back in, my shirt smelled as if oil had been sitting with water (like a sulfur or just a bad smell). my radiator has a crack in it so i leak from there so i cant gauge it through the motor. if i rev the motor high, i burn black smoke since i am on the rich side.
im going to do a compression check sometime this weekend to see if i see any odd numbers. my car sputters sometimes from either my ignition or bad fuel. i have to get some additive to my fuel incase i have water in there from bad gas. but again i dont know if its from the gas or water going in the combustion

well its a blown head gasket or both. i pulled the radiator cap and i see milky liquid in it and in the bypass resovoire. guess ill be ripping the upper end back off next weekend. on a positive note, ill take the heads in at the race shop and get some work done on them and wrap my exhaust in heat tape. thanks for the input guys.
