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..

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

and it will run better if it has the correct dated heads..
