    Question 350 antifreeze leakage

    Hi im new here. I have a new chevy motor that i had bored out and new pistons, crank, cam, heads and so on. I just started it for the first time today and its leaking tons of water (I put water into the cooling system in case something leaked) out the exhaust. I checked and there is no water in the oil anywhere but lots is coming out the exhaust. I was wondering if i got a bad head. Any suggestions? Thanks

    sounds like a head gasket, if there isn't any water in the oil.
