Casting date on heads

[Eric F]

My 70 Road Runner has the original block. Cast date 2/14/70. Car scheduled build date 7/08/70.
The heads that came with the car are 08/08/9. August of 69. Could they be original or is the date too early for the car?

They could be original, in my opinion.

6 months prior to engine, that's pushing it, but entirely possible. You didn't post the build date of your engine. Also there is also 5 months between the engine cast date and the build date of the car. All is entirely possible. Are the heads correct 906's? End of year production, they were always gathering unused parts.
