Uncorked the intake manifold the other day on a basically fresh motor, and the head on the passenger side had a threaded bung/bushing (just like the one on the drivers side, at the rear of the head, for the temp sender) at the FRONT

coolant port. How can this be removed? does the head need to come off and take it to a machine shop? Can I put this in the rear port of the passenger head and essentially run two temp senders (one factory, and one for a Sunpro gauge?
