The 22R should be a straight bolt in because IIRC the USA had this engine in its standard RA60 (not RA65) Celica's. Depending on the series of 22R engine, early or late (you want early) a 20R head will bolt on to one of these, and that flows heaps better than the 22R head and ups your compression a few points as well too, bonus !.
Maybe that's why TDFSM would like to buy it !
