I am working on a friends FJ40. He doesn't know anything about engines, etc., so I am trying to figure this out. It is a 1972 fj40 but he was told when he bought it that the engine was from a 1974 fj40. Long story short, the head cracked and needs to be replaced. After some long searching here I still can't figure out if this is an F head or a 2F head. It has the F valve cover, a one piece rocker arm assembly, and did not have any copper tube running up to the head. The block also does not have any tube coming out by the #3 cylinder either. Is this a transition engine that I have seen some posts about? I don't have the head right now because it is at the shop. I can run and get it if I must get codes. Does anyone else have some pictures I could see so I could compare to what I have. Hope that is enough info. I don't know very much about these trucks.
Thanks,
Dan
