There will literally be a "T" casted into the top on the head. I believe that it refered to Tonowanda, casting facility? I personally have found them on the "truck" engines, replacement engines and even some passenger cars. Don't forget to look on 327's. They are just a better casting. Now if they ever made a 520X head that would be great!! LOL Hope this helped.

How would a set of canada castings work ?. I heard they were very rare and hard to find ,but i know someone (me) who has a pair that used to be Garley Daniels heads.
