Oil spray near bottom of head?

Most likely HG. I blew mine out on the same spot.

I used a sixteen point socket, if you are talking about the actual head bolts.
A 16 point socket, eh? I would like to see one of those! I think you got a little confused, it should be a 12 point socket.

See the other head thread, I listed all the sizes there.
