Changed head gasket...

[Bones566]

I'm going to a friends of mines house tomorrow to help him figure out what's wrong with his 97 M3. He said it overheated on his son so he removed the head to change the gasket. He Reassembled and now it will only run while holding a his hand over the intake. I haven't look at it yet, I just wanted some ammo to throw at it before I go over there. Any suggestions?
