From my research, the 2843906 heads were manufactured for the '68, '69 and '70 model years only. They were used on the B/RB engines.

Thanks for the response. I know they were made for 68-70 B/RB engines. I'd like to know how to date them, as to when they were cast.

Thanks

Ok i've found those cast numbers, they are 11228 and 11268.
I guess they are way off for my Superbird..

Thanks for the help

i guess i'll have to try and fix the original one..

I'm all for correctness, but since all 906's are the same and you can't see those dates unless you remove a valve cover...

But he'll sleep better at night knowing that his heads have the "correct nummers"

I didn't care about the date code when I located my heads. I was just happy to find a good set.
