On another board someone posted the following: "When I first purchased my 82 FJ, I knew the head was damaged (the white and blue smoke was a obvious indication). I didn't know that finding a replacement for the 2F motor was going to be a serious problem however. Luckly, one of my motorhead friends knew the history of the Toyota 2F motor. Since Toyota bought the remaining stock of GM motors to create the 2F, a new (yes new) GM head will fit perfectly on the 2F. So, for an option beyond spending a fortune on a remanufactured head and not knowing for sure what you are getting. Try the GM part instead. I think the gasket seals are also the same-try your local motor shop if interested. I will lookup the GM part a post it later. " I think he's full of it but don't know for sure. What's the truth? If he's right, it'd make bolt fuel injection a lot easier wouldn't it?
