When I changed my head gasket I had the same problem. Disconnect the egr from the left exhaust manifold and then weave it threw all the wires While still connected to the back of the intake manifold. Make sure to have the intake manifold side tight when putting it back together cause I put it the exhaust manifold side on first and I cant tighten it to the intake so it throws a code now for leaking....
Hope it help and I wasn't too late.
