im about to pick up a 92 jdm b16 head and was wondering what the code is on it? also what is the difference between that and a 00 si head? and last is it has a itr intake manifold on it and was wondering how to identify that too? thanx!!!!!! drew

 

all b16/itr heads are stamped pr3-xx. all b16 heads are identical with the exception of the earlier years having slightly different valvetrain.
