my 4.2 sucked when i got it, i did the nutter bypass, added a weber carb, and re timed it to 9* and it runs like a dream now, starts right up unless its super cold. Whenever something goes wrong i just reset the carb and adjust a few screws, sometimes change the float level and shes back running great again. No computer to mess with. I was looking at the 4.0 head swap to the 4.2 though, i heard there are great power and MPG gains. If you get a good deal on the 4.2 go for it and read up on the nutter bypass and get a good carb. It takes a little time but its cake once you got it down.
I can't bear the thought of losing, I dread the attention winning brings
