1961 Head & Engine Numbers
Adjusting solid lifters today and noticed the passenger side head (casting number 3774692) has a date of 'E1 1' May 1st, 1961.
The engine stamp pad is the 108523F0502CU , the next day May 2nd, 1961.
Is this possible ??
The car is all original as far as I know but those two dates seem mighty close together!

That would be considered an extreme case of Just In Time manufacturing, long before anybody knew what JIT was.
I would say, no, it isn't possible. Maybe you have a restamp, or somebody went searching for some approx correct dated heads at one time for the car.

I have heard of this happening with engine blocks but not with heads. I guess it is possible, but a lot needs to happen to that raw casting in just 24 hours (machining, guides, assembly, movement to engine assembly area).

Yes, it is, although it's unusual. The Saginaw Foundry was only 45 minutes away, and a dedicated internal fleet of trucks that ran 24/7 hauled 55,000 castings every day to Flint Engine. We have documented many instances of castings that were machined/assembled the day after they were cast, and a few that were machined/assembled the same day (1st shift at Saginaw, 2nd shift at Flint Engine).
