Well, I found another N47 head at the local junkyard in a 1980 280zx. The cam cover is missing and it looks like it's been baking in the sun forever. It's also missing some springs and other components from the head, but the cam and cam caps are still there. It would still cost me about $100 bucks even though it's incomplete and I would have to pull the head myself. Do you think I should wait to buy a complete head? I also found a N42 head complete but it's about 5 hours away from me in Arizona.
