I have a '78 360 with smog heads in my '68 Satellite that the last owner put in. I'm up in San Jose, CA and currently building a 451 big block for my car. Once that motor is done in the next 3-4 months I'll be looking to offload the 360. You can have the whole thing front to back including the Torqueflight 904 and all pumps, pulleys, etc cheap if you want and don't end up finding an earlier year motor. I know it's a bit far, but to help a fellow mopar head out I can let it all go for a few hundred bucks since I know you'll have to do the transport. The previous owner told me this 360 came out of a '78 Dodge Truck (D100 is what I always tell the part stores) and he rebuilt it to stock specs. Supposedly only 40K miles on it when I got it and I've only put another 1K on it before I decided to build the big block.
I've done some research on the smog heads and supposedly with some brass inserts (instead of full port job per a mopar action article I read) they are supposed to flow pretty good. Mine are stock with nothing done to them so they're not that great right now, but I've heard they can be made to be.
Also on my 360 I recently put in a new carter mechanical fuel pump, water pump, coil, plugs, wires, cap/rotor, and mopar distributor. I asked for a water pump for a '78 360 at the auto parts store and they didn't have it. They did have one listed for a 318 motor (high volume with 8 veins instead of 6) and it fit perfect when I installed it.
