Re: 4.0 head conv cost?
Don't forget you'll need the 4.0 exhaust header. I'm at about $300 including the head (with valves,springs,cover...), exhaust header, all necessary gaskets, material to fill the water jackets and fresh oil and coolant. I've got a friend with a machine shop so the valve job won't cost me too much. I was willing to wait and got a guarrantied head from a local wrecker that deals only in Jeeps. If I couldn't wait, another bone yard was trying to get $400 out of me for just the head and he had no clue what kind of shape it was in.
