I have a 88 22re the heads messed up on. One of my friends is going to give me a 22r motor out of an 85 how much trouble or what hassles would be with putting this motor in, in place of the one i have now.

 

Everything should be the same. 85+ is all the same as far as I have read. From what I have read the head is the same from carb to EFI on 85+. I am doing a similar swap, but I want to go from carb to EFI in the future, so I was concerned about having to switch the head when I do so.

Technically not legal to put an older motor in a newer vehicle, but I'll never tell, and maybe laws in your state are different then communist Cali.
