On the 5-cylinder I just did I had the tank it, check for flat, and pull the valve stem seals (I had pulled the valves). The stem seals need replaced, the head needs to be flat and it needs to retain the factory mill pattern or if shaved have a similar level of not-smooth, it is good to have valve seats touched up (not enough materials to grind them) and IT MUST be CLEAN and stay that way. Have them run spark plug tap on the holes to make sure they are still viable.

It does not have a valve cover gasket. It uses microns thick coating of anaerobic sealant put on with a roller before you three-stage tighten 50+ bolts on the cam cover.

Oh, and get and angle torque gauge (about $15 on Amazon) and be prepared to scare the crap out of yourself with the REALLLLLLLY long final angle torque on those head bolts.
