Air pocket in head casting?
Just happened to notice what looks like an air pocket in the intake runner of my head, as I was getting ready to torque them down. Putting the motor back together. At first I thought maybe a stud hole was drilled too far but it does not line up with the stud. Anyone seen anything like this and is it a problem or fixable? I wondered if there was water on the other side of the hole. Gonna have my machinist take a look at it monday.

I stuck a wire in it and it's about 1/4 in deep. I probed around a little the sides of it to see if i could push the wire through like to a water jacket but it didnt go any deeper. I'll snap another pic and post it and see what the machinist thinks. I wanted to torque these heads on this weekend.

Last night i didnt think it lined up with the stud but this morning its looking like thats what it could be. It's hard to see in these pics.

Machinist said the casting was a little shallow near the stud. Studs are sealed. He said put it together and dont worry about it. It wont affect anything. Now back to the garage. thanks guys.
