I would say re-torque the head to foot pounds with a known good TW. If you see movement, change the oil (since oil/coolant could have mixed) and try again. If that does not work, tear it down to inspect the head gasket and head&block surfaces. If the stuff is shooting out above the Head Gasket, I would think it is most likely the machining work on the head.
I've no experience with copper spray but with the above posts suggesting this was a nono, keep this in mind while inspecting.
