This may seem like a dumb question but, I have a set of 706 heads on my build that I just fired up today. As I was pouting in coolant is was leaking by the rear of the drivers head. As I felt around the rear of the head I could feel the coolant coming from a hole at the rear of the head (facing the firewall). Is there supposed to be some sort of plug back there?

There's a freeze plug on either end of the head.

Freeze plug is bone dry. Something back there is leaking as I'm putting coolant in. Like a stream. I would imagine the head gasket couldn't do this?

Only other thing I can think of would be the steam vent. I wouldn't think that a bad head gasket would let unpressurized coolant run out like that. Unless someone really messed up the install.

Get a small mirror and high powered flashlight and shine it back there and angle the mirror. You should be able to see where the leak is pretty easily.

Steam tube on that side was hand tight. Lol
