Default new cam, small problem

Just installed my cam/heads and when I went to drive the car it started over heating. Bled the air out of the cooling system and was filling the radiator while the car was running (so I could keep filling it as the water was being pulled through) and out of no where I see smoke and hear water hitting my passenger header. Sure enough I look under the car and there is water pouring onto the end of the header. No water is being spilled from the engine inside the engine bay as far as I can see so I'm really confused. Any Ideas?

My best guess is that you have a blown head gasket and water is squeezing out at the back of the head. The fact that it happened after a cam install is coincidence.

It's not a coincidence that it happened after he also did the heads though.

What gaskets did you use?

I got NEW GM factory steel gaskets and it's more than seeping it kinda just poured out. I was thinking that maybe the coolant stop or whatever they're called on the back of the head maybe loose or something. I ran it twice and drove it once before this ever happened
