I just removed the head on mine. In order to be positive you would have to take off the pully, which means belts and lower timing cover. At minimum the pully bolt to see if the key is staright up (that one bolt can be hard to remove).

If not, if everything was lined up before you took off the head and you didn't move the crank position, I say go for it.

My head has leaky valve seals and a f'd up plug hole. I think I'll just swap the running motor and tranny from the car we're junking, since that motor works fine and has less miles.
