Thanks for the insight...the only reason I was considering going this way is because the head is free... I already have a headgasket set, timing belt, and waterpump, and I can do this work myself. If I were to buy the z6 head, I would have to convert to OBD1, find the parts and have them shipped, and do the wiring. If I had someone close who could help me with the mini me setup I would go for it, but on my own it is a little over my head.
