I have been lurking on the forum for quite sometime reading and learning a lot. My car needs a head gasket and possible head confirmed by Lexus dealer. I want to swap in the 4th gen engine into my 3rd gen, but i can not find or (maybe i searched incorrectly), if it matters which 4th gen engine it needs to be, IE (FU,EU engine, or 5th digit B.n)? I apologize if this has been discussed all ready. Thanks for the help.
