there are numbers on the head that tell you what month and year the motor was made in.

i.e.
if it says

0/9 9/1 <----- (these numbers are circled)

that means its a 92 motor made in september of 91 ( anything after 0/6 is the next year up)

but as SPOOLIN said... any motor can be any OBD for the most part.
Hope this helped
