If it says 302 then that's what it is, the actual casting number that would tell you the application is located under the head, by one of the pushrod holes. You can only see it when the intake is off, with a mirror. The casting number is more important than the date code, as there were differences between the combustion chambers and ports.

You can tell a little bit from what type of rocker setups it has, the pedestal rockers were from later motors.


check this website out, it has some info about where to look for the number.

If you can see the casting number, here is a website with all of the casting numbers.

Click on this: [url]www.mre-books.com click on Ford books, probably would be a good idea to get the book.

The 2J14 appears to be the casting date code. That would have it cast on Sept 14,1972. Making it, most likely, a 1973 302 head.

As always thanks for the good info guys.
