L78 head dates

[bergy]

Remember that the head dates are cast in at the foundry. To be the same day - the head had to be cast, work its way all the way through cooling and finishing (6-7 hours at best), ship to the motor plant (next door), get all the way through head machining & build, transport to the engine build line, and install. All that had to happen in 16 to 18 hours (start of foundry first shift to end of motor plant second shift). Not impossible, but WHEW!
