The upper and lower intake gaskets need to be replaced, Also the valvecover gasets, and a few misc o-rings. It is a good idea to replace the oil pump drive seal while the job is being preformed as it is right there and known to leak. Probably looking at about $700.00 to complete the repair. It is about a 6 hour job as far as labor goes.
If it is leaking I would not drive it anymore than you have to because those are known to leak internaly as well and coolant is hard on bearings.
