Corolla All-Trac SEDAN????

Okay folks, I need information on this one. I just found a 1989 Corolla All-Trac Sedan. It's a 4AFE, 5 speed, Air Tilt, Tach Dash, Ice Blue with a Dark Blue interior. Is this All Wheel Drive or part time? It has a Differential Lock Button on the dash and everything works fine. Pretty cool car. Handles well and runs great. Anybody ever seen one? I knew about the wagons but never saw the sedan.

I saw one just the other day, we pulled up behind it and I saw the "4WD" emblem and I kind of went "no way!" I didn't know they made sedan versions in 4WD either, until then.

I just bought a Corolla All-Trac sedan actually, but unfortunately, it had a BHG for way too long and ate away the coolant passage right up to the edge of the combustion chamber, so I need to find a head for this 4A-FE. I have an FX-16/GTS/thing parts car, but unless someone thinks the 4A-GE engine swap is straightforward, I'm going to try to fix this FE. Anyone have a 4A-FE head for sale?

I have one, anyone else seen any forsale? I"m looking for another one for parts or something...
