Carl
I just looked up my head casting number and it is indeed from an earlier model. A 1956.
Thanks
The same head casting code was used from 1956-1963 (3836848).
What is your block casting code?
What are your block and head casting dates?

shown here )? These this get swapped around over the years (unfortunately).
