Was wondering if a Pr3-2 was a second gen b16 head from japan? I know the b16 and itr share same head code (Pr3).....what is the (-2) mean? Does anyone also have a link to where I can find codes to identify heads? Thanks.

 

what year is the stamping on it.....
89-91 are 1st gen head but also some 91 late october are 2nd gen so its hard to say...
